2.0 Gb, DDR3, 64 M x 32 Integrated Module (IMOD)
FUNCTIONAL DESCRIPTION
The DDR3 SDRAM uses double data rate architecture to achieve high speed operation. The double data rate (DDR) architecture is an 8n prefetch with an interface designed to transfer two data words per clock cycle at the I/O pins. A single READ or WRITE access for the DDR3 SDRAM consists of a single 8n-bit-wide, one-clock-cycle data transfer at the internal memory core and eight corresponding n-bit-wide, one-half-clock-cycle data transfer at the I/O pin. The differential strobes (LDQSx, LDQSx\, UDQSx, UDQSx\) is transmitted externally, along with data, for use in data capture at the DDR3 SDRAM input receiver. DQS is center-aligned with data for WRITEs. The READ data is transmitted by the DDR3 SDRAM and edge-aligned to the data strobes. The DDR3 SDRAM operates from a differential clock (CKx, CKx\). The crossing of CK going HIGH and CK\ going LOW is referred to as the positive edge of Clock (CK). Control, Command, and Address signals are registered at every positive edge of CK. Input data is registered on the first rising edge of DQS after the WRITE preamble, and output data is referenced on the first rising edge of DQS after the READ preamble. READ and WRITE accesses to the DDR3 SDRAM are burst-oriented. Accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of an ACTIVATE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVATE command are used to select the bank and the starting column location for the burst access. DDR3 SDRAM devices use READ and WRITE BL8 and BC4. An AUTO PRECHARGE function may be enabled to provide a self-timed ROW PRECHARGE that is initiated at the end of the burst access. As with standard DDR SDRAM devices, the pipelined, multi-bank architecture of the DDR3 SDRAM allows for concurrent operation, thereby providing high bandwidth by hiding ROW PRECHARGE and ACTIVATION time. A SELF REFRESH mode is provided for all temperature grade offerings along with AUTO SELF REFRESH for Industrial product, as well as, powersaving, POWER-DOWN mode.
INDUSTRIAL TEMPERATURE
The industrial temperature (I) device requires the case temperature not exceed -40˚C or +85˚C. JEDEC specifications require the REFRESH rate to double when Tc exceeds +85˚C; this also requires use of the hightemperature SELF REFRESH option. Additionally, ODT resistance and the INPUT/OUTPUT impedance must be derated when the Tc is +85˚C.
EXTENDED TEMPERATURE
The Extended temperature (E) device requires the case temperature not exceed -40˚C or +105˚C. JEDEC specifications require the refresh rate to double when Tc exceeds +85˚C; this also requires use of the hightemperature SELF REFRESH option. Additionally, ODT resistance and the INPUT/OUTPUT impedance must be derated when the Tc is 85˚C.
MILITARY, EXTREME OPERATING TEMPERATURE
The Mil-Temp (M) device requires the case temperature not exceed -55˚C or +125˚C. JEDEC requires the REFRESH rate double when Tc exceeds +85˚C and LDI recommends an additional derating as specified in this document as to properly maintain the DRAM core cell charge at temperatures above Tc>105˚C.

NOTES
1. 2. 3. 4. Parameters are applicable with 0˚C ≤ Tc ≤ +95˚C and Vcc/VccQ = + 1.5V ± 0.075V. All voltages are referenced to Vss. Output timings are only valid for RON34 output buffer selection. Unit tCK (AVG) represents the actual tCK (AVG) of the input clock under operation. Unit CK represents one clock cycle of the input clock, counting the actual clock edges. AC timing and ICC tests may use a VIL-to-VIH swing of up to 900mV I the test environment, but input timing is still referenced to VREF (except tIS, tIH, tDS, and tDH use the AC/DC trip points and CK, CK\ and DQS, DQS\ use their crossing points). The minimum slew rate for the input signals used to test the device is 1V/ns for single-ended inputs and 2V/ ns for differential inputs in the range between VIL (AC) and VIH (AC). All timings that use time-based values (ns, μs, ms) should use tCK (AVG) to determine the correct number of clocks (Table 50 uses CK or CK (AVG) interchangeably). In the case of non-interger results, all minimum limits are to be rounded up to the nearest whole integer. The use of STROBE or DQSDIFF refers to the DQS and DQS\ differential crossing point when DQS is the rising edge. The use of CLOCK or CK refers to the CK and CK\ differential crossing point when CK is the rising edge. This output load is used for all AC timing (except ODT reference timing) and slew rates. The actual test load may be different. The output signal voltage reference point is VccQ/2 for single-ended signals and the crossing point for differential signals. When operating in DLL disable mode, LOGIC Devices, Inc. (LDI) does not warrant compliance with normal mode timings or functionality. 24. 10. The clock’s tCK (AVG) is the average clock over any 200 consecutive clocks and tCK (AVG) MIN is the smallest clock rate allowed, with the exception of a deviation due to clock jitter. Input clock jitter is allowed provided it does not exceed values specified and must be of a random Gaussian distribution in nature. Spread spectrum is not included in the jitter specification values. However, the input clock can accommodate spread-spectrum at a sweep rate in the range of 20-60kHz with and additional 1% of tCK (AVG) as a long-term jitter component; however, the spread-spectrum may not use a clock rate below tCK (AVG) MIN. The clock’s tCH (AVG) and tCL (AVG) are the average half clock period over any 200 consecutive clocks and is the smallest clock half period allowed, with the exception of values specified and must of a random Gaussian distribution in nature. The period jitter (tJITPER) is the maximum deviation in the clock period from the average or nominal clock. It is allowed in either the positive or negative direction.
tCH (ABS) is the absolute instantaneous clock high pulse width as measured from one rising edge to the following falling edge. tCL (ABS) is the absolute instantaneous clock low pulse width as measured from one falling edge to the following rising edge.
deviate from one cycle to the next. It is important to keep cycle-to-cycle jitter at a minimum during the DLL locking time. 17. The cumulative jitter error (tERRnPER), where n is the number of clocks between 2 and 50, is the amount of clock time allowed to accumulate consecutively away from the average clock over n number of clock cycles.
tDS (base) and tDH (base) values are for a single-ended 1V/ns DQ slew rate and 2V/ns for differential DQS, DQS\ slew rate.

These parameters are measured from a data signal (DM, DQ0, DQ1 … DQn and so forth) transition edge to its respective data strobe signal (DQS, DQS\) crossing. The setup and hold times are listed converting the base specification values (to which derating tables apply) to VREF when the slew rate is 1V/ns. These values, with a slew rate of 1V/ns are for reference only. When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJITPER (larger of tJITPER (MIN) or tJITPER (MAX) of the input clock (output deratings are relative to the SDRAM input clock). Single-ended signal parameter. The SDRAM output timing is aligned to the nominal or average clock. Most output parameters must be derated by the actual jitter error when input clock jitter is present, even when within specification. This results in each parameter becoming larger. The following parameters are required to be derated by subtracting tERR10PER (MAX); tDQSCK (MIN), tLZ (DQS) MAX, tLZ (DQ) MAX, and tAON (MAX). The parameter tRPRE (MIN) is derated by subtracting tJITPER (MAX), while tRPRE (MAX) is derated by tJITPER (MIN). The maximum preamble is bound by tLZDQS (MAX). These parameters are measured from a data strobe signal (DQS, DQS\) crossing to its respective clock signal (CK, CK\) crossing. The specification values are not affected by the amount of clock jitter applied, as these are relative to the clock signal crossing. These parameters should be met whether clock jitter is present or not. The tDQSCK DLL_DIS parameter begins CL + AL - 1 cycles after the READ command. The maximum postamble is bound by tHZDQS (MAX). Commands requiring a locked DLL are: READ (and RDAP) and synchronous ODT commands. In addition, after any change of latency tXPDLL, timing must be met.

jitter specifications are satisfied. For example, the device will support tnRP (nCK) = RU (tRP)/tCK[AVG]) if all input clock jitter specifications are met. This means for DDR2-800; 6-6-6, of which tRP = 15ns, the device will support tnRP = RU (tRP/tCK [AVG]) = 6 as long as the input clock jitter specifications are met. That is, the PRECHARGE command at T0 and the ACTIVATE command at T0+6 are valid even if six clocks are less than 15ns due to input clock jitter. 32. During READs and WRITEs with AUTO PRECHARGE, the DDR3 SDRAM will hold off the internal PRECHARGE command until tRAS (MIN) has been satisfied. When operating in DLL disable mode, the greater of 4CK or 15ns is satisfied for tWR. The start of the write recovery time is defined as follows: • For BL8 (fixed by MRS and OTF): Rising clock edge four clock cycles after WL. • For BC4 (OTF): Rising clock edge four clock cycles after WL. • For BC4 (fixed by MRS): Rising clock edge two clock cycles after WL. 35. RESET\ should be LOW as soon as power starts to ramp to ensure the outputs are in HIGH-Z Until RESET\ is LOW, the outputs are at risk of driving the bus and could result in excessive current, depending on the bus activity. The refresh period is 64ms when Tc is less than or equal to 85˚C. This equates to an average refresh rate of 7.8124μs. However, nine REFRESH commands should be asserted at least once every 70.3μs. When Tc is greater than 85˚C, the refresh period is 32ms and when Tc is greater than 105˚C, the refresh period is 24ms. 41. 42. 40. 37. Although CKE is allowed to be registered LOW after a REFRESH command when tREFPDEN (MIN) is satisfied, there are cases where additional time such as tXPDLL (MIN) is required. ODT turn-on time MIN is when the device leaves HIGH-Z and ODT resistance begins to turn on. ODT turn-on time maximum is when the ODT resistance is fully on. The ODT reference load is shown in Figure 23. Half-clock output parameters must derated by the actual tERR10PER and tJITDTY when input clock jitter is present. This results in each parameter becoming larger. The parameters tADC (MIN) and tAOF(MIN) are each required to be derated by subtracting both tERR10PER (MAX) and tJITDTY (MAX). The parameters tADC (MAX) and tAOF (MAX) are required to be derated by subtracting both tERR10PER (MAX) and tJITDTY (MAX). ODT turn-off time minimum is when the device starts to turn off ODT resistance. ODT turn-off time maximum is when the SDRAM buffer is in HIGH-Z. The ODT reference load is shown in Figure 24. This output load is used for ODT timings (see Figure 31). Pulse width of an input signal is defined as the width between the first crossing of VREF (DC) and the consecutive crossing of VREF(DC). Should the clock rate be larger than tRFC(MIN), an AUTO REFRESH command should have at least one NOP command between it and another AUTO REFRESH command. Additionally, if the clock rate is slower than 40ns (25MHz) all REFRESH commands should be followed by a PRECHARGE ALL command.

COMMAND AND ADDRESS SETUP, HOLD, AND DERATING
The total tIS (setup time) and tIH (hold time) required is calculated by adding the data sheet tIS(base) and tIH (base) values (Tables 51) to the ∆tIS and ∆tIH derating values (Table 52), respectively.
Although the total setup time for slow slew rates might be negative, a valid input signal is still required to complete the transition and to reach VIH(AC)/VIL(AC) (see Figure 14 for input signal requirements). For slew rates which fall between the values listed in Table 52 and Table 53, the derating values may be obtained by linear interpolation.
Setup (tIS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VREF(DC) and the first crossing of VIH(AC) MIN. Setup (tIS) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VREF(DC) and the first crossing of VIL(AC) MAX. If the actual signal is always earlier than the nominal slew rate line between the shaded “VREF(DC)-to-AC region”, use the nominal slew rate for derating value (see Figure 25). If the actual signal is later than the nominal slew rate line anywhere between the shaded “VREF(DC)-to-AC region”, the slew rate of a tangent line to the actual signal from the AC level to the DC level is used for the derating value (see Figure 27).
Hold (tIH) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VIL(DC) MAX and the first crossing of VREF(DC). Hold (tIH) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VIH(DC) MIN and the first crossing of VREF(DC). If the actual signal is always later than the nominal slew rate line between the shaded “DC-to-VREF(DC) region”, use the nominal slew rate for derating value (see Figure 26). If the actual signal is earlier than the nominal slew rate line anywhere between the shaded ”DC-to-VREF(DC) region”, the slew rate of a tangent line to the actual signal from the DC level to the VREF(DC) level is used for the derating value (see Figure 28).
