cache applications, etc. The chip’s 16bank architecture is optimized for sustainable high-speed operation. The DDR I/O interface transfers two data bits per clock cycle at the I/O balls. Output data is referenced to the READ strobes. Commands, addresses, and control signals are also registered at every positive edge of the differential input clock, while input data is registered at both positive and negative edges of the input data strobes. Read and write accesses to the RL3 device are burst-oriented. The burst length (BL) is programmable to 2, 4, or 8 by a setting in the mode register. The device is supplied with 1.35V for the core and 1.2V for the output drivers. The 2.5V supply is used for an internal supply. Bank-scheduled refresh is supported with the row address generated internally. The 168-ball FBGA package is used to enable ultra-high-speed data transfer rates. General Notes • The functionality and the timing specifications discussed in this data sheet are for the DLL enable mode of operation. • Any functionality not specifically stated is considered undefined, illegal, and not supported, and can result in unknown operation. • Nominal conditions are assumed for specifications not defined within the figures shown in this data sheet. • Throughout this data sheet, the terms "RLDRAM," "DRAM,” and "RLDRAM 3" are all used interchangeably and refer to the RLDRAM 3 SDRAM device. • References to DQ, DK, QK, DM, and QVLD are to be interpeted as each group collectively, unless specifically stated otherwise. This includes true and complement signals of differential signals. • Non-multiplexed operation is assumed if not specified as multiplexed. • A X36 Device supplies four QK/QK# sets. One per 9 DQs. If a user only wants to use two QK/QK# sets, this is allowed. The user needs to use QK0/QK0# and QK1/QK1#. QK0/QK0# will control DQ[8:0] & DQ[26:18]. QK1/QK1# will control DQ[17:9] & tQKQ02, tQKQ13. The DQ[35:27]. The QK to DQ timing parameter to be used would be unused QK/QK# pins should be left floating.

During a MODE REGISTER SET, the address inputs define the register settings along with BA[3:0]. They are sampled at the rising edge of CK. BA[3:0] Input Bank address inputs: Select the internal bank to which a command is being applied. CK/CK# Input Input clock: CK and CK# are differential input clocks. Addresses and commands are latched on the rising edge of CK. CS# Input Chip select: CS# enables the command decoder when LOW and disables it when HIGH. When the command decoder is disabled, new commands are ignored, but internal operations continue. DQ[35:0] I/O Data input: The DQ signals form the 36-bit data bus. During READ commands, the data is referenced to both edges of QK. During WRITE commands, the data is sampled at both edges of DK. DKx, DKx# Input Input data clock: DKx and DKx# are differential input data clocks. All input data is referenced to both edges of DKx. For the x36 device, DQ[8:0] and DQ[26:18] are referenced to DK0 and DK0#, and DQ[17:9] and DQ[35:27] are referenced to DK1 and DK1#. For the x18 device, DQ[8:0] are referenced to DK0 and DK0#, and DQ[17:9] are referenced to DK1 and DK1#. DKx and DKx# are free-running signals and must always be supplied to the device. DM[1:0] Input Input data mask: DM is the input mask signal for WRITE data. Input data is masked when DM is sampled HIGH. DM0 is used to mask the lower byte for the x18 device and DQ[8:0] and DQ[26:18] for the x36 device. DM1 is used to mask the upper byte for the x18 device and DQ[17:9] and DQ[35:27] for the x36 device. Tie DM[1:0] to VSS if not used. TCK Input IEEE 1149.1 clock input: This ball must be tied to VSS if the JTAG function is not used. TMS, TDI Input IEEE 1149.1 test inputs: These balls may be left as no connects if the JTAG function is not used. WE#, REF# Input Command inputs: Sampled at the positive edge of CK, WE# and REF# (together with CS#) define the command to be executed. RESET# Input Reset: RESET# is an active LOW CMOS input referenced to VSS. RESET# assertion and deassertion are asynchronous. RESET# is a CMOS input defined with DC HIGH ≥ 0.8 x VDD and DC LOW ≤ 0.2 x VDDQ. ZQ Input External impedance: This signal is used to tune the device’s output impedance and ODT. RZQ needs to be 240Ω, where RZQ is a resistor from this signal to ground. QKx, QKx# Output Output data clocks: QK and QK# are opposite-polarity output data clocks. They are free-running signals and during READ commands are edge-aligned with the DQs. For the x36 device, QK0, QK0# align with DQ[8:0]; QK1, QK1# align with DQ[17:9]; QK2, QK2# align with DQ[26:18]; QK3, QK3# align with DQ[35:27]. For the x18 device, QK0, QK0# align with DQ[8:0]; QK1, QK1# align with DQ[17:9]. QVLDx Output Data valid: The QVLD ball indicates that valid output data will be available on the subsequent rising clock edge. There is a single QVLD ball for the x18 device and two, QVLD0 and QVLD1, for the x36 device. QVLD0 aligns with DQ[17:0]; QVLD1 aligns with DQ[35:18]. MF Input Mirror function: The mirror function ball is a DC input used to create mirrored ballouts for simple dual-loaded clamshell mounting. If the ball is tied to VSS, the address and command balls are in their true layout. If the ball is tied to VDDQ, they are in the complement location. MF must be tied HIGH or LOW and cannot be left floating. MF is a CMOS input defined with DC HIGH ≥ 0.8 x VDD and DC LOW ≤ 0.2 x VDDQ.

IDD mesurements use tCK (MIN), tRC (MIN), and minimum data latency (RL and WL). 3. Input slew rate is 1V/ns for single ended signals and 2V/ns for differential signals. 4. Definitions for IDD conditions: • LOW is defined as VIN ≤ VIL(AC)MAX. • HIGH is defined as VIN ≥ VIH(AC)MIN. • Continuous data is defined as half the DQ signals changing between HIGH and LOW every half clock cycle (twice per clock). • Continuous address is defined as half the address signals changing between HIGH and LOW every clock cycle (once per clock). • Sequential bank access is defined as the bank address incrementing by one every tRC. • Cyclic bank access is defined as the bank address incrementing by one for each command access. For BL = 2 this is every clock, for BL = 4 this is every other clock, and for BL = 8 this is every fourth clock. 5. CS# is HIGH unless a READ, WRITE, AREF, or MRS command is registered. CS# never transitions more than once per clock cycle. 6. IDD parameters are specified with ODT disabled. 7. Upon exiting standby current conditions, at least one NOP command must be issued with stable clock prior to issuing any other valid command.

All voltages referenced to VSS (GND). 2. The nominal value of VREF is expected to be 0.5 × VDDQ of the transmitting device. VREF is expected to track variations in VDDQ. 3. Peak-to-peak noise (non-common mode) on VREF may not exceed ±2% of the DC value. DC values are determined to be less than 20 MHz. Peak-to-peak AC noise on VREF should not exceed ±2% of VREF(DC). Thus, from VDDQ/2, VREF is allowed ±2% VDDQ/2 for DC error and an additional ±2% VDDQ/2 for AC noise. The measurement is to be taken at the nearest VREF bypass capacitor.

All voltages referenced to VSS (GND). 2. The receiver will effectively switch as a result of the signal crossing the AC input level, and will remain in that state as long as the signal does not ring back above/below the DC input LOW/HIGH level. 3. Single-ended input slew rate = 1 V/ns; maximum input voltage swing under test is 900mV (peak-to-peak).
