DATA
CIRCUIT
This highly reliable process coupled with innovative circuit
design techniques including ECC (SEC-DEC: Single Error
Correcting-Double
Error
Detecting),
yields
highperformance and low power consumption devices. When
CS1# is HIGH (deselected) or when CS2 is LOW
(deselected), or when CS1# is LOW, CS2 is HIGH and
both LB# and UB# are HIGH, the device assumes a
standby mode at which the power dissipation can be
reduced down with CMOS input levels.
Easy memory expansion is provided by using Chip Enable
and Output Enable inputs. The active LOW Write Enable
(WE#) controls both writing and reading of the memory. A
data byte allows Upper Byte (UB#) and Lower Byte (LB#)
access.

FUNCTION DESCRIPTION
SRAM is one of random access memories. Each byte or word has an address and can be accessed randomly. SRAM
has three different modes supported. Each function is described below with Truth Table.
STANDBY MODE
Device enters standby mode when deselected (CS1# HIGH or CS2 LOW or both UB# and LB# are HIGH). The input
and output pins (I/O0-15) are placed in a high impedance state. The current consumption in this mode will be ISB1 or
ISB2. CMOS input in this mode will maximize saving power.
WRITE MODE
Write operation issues with Chip selected (CS1# LOW and CS2 HIGH) and Write Enable (WE#) input LOW. The input
and output pins (I/O0-15) are in data input mode. Output buffers are closed during this time even if OE# is LOW. UB#
and LB# enables a byte write feature. By enabling LB# LOW, data from I/O pins (I/O0 through I/O7) are written into the
location specified on the address pins. And with UB# being LOW, data from I/O pins (I/O8 through I/O15) are written
into the location.
READ MODE
Read operation issues with Chip selected (CS1# LOW and CS2 HIGH) and Write Enable (WE#) input HIGH. When
OE# is LOW, output buffer turns on to make data output. Any input to I/O pins during READ mode is not permitted. UB#
and LB# enables a byte read feature. By enabling LB# LOW, data from memory appears on I/O0-7. And with UB#
being LOW, data from memory appears on I/O8-15.
In the READ mode, output buffers can be turned off by pulling OE# HIGH. In this mode, internal device operates as
READ but I/Os are in a high impedance state. Since device is in READ mode, active current is used.
ERROR DETECTION AND ERROR CORRECTION
Independent ECC per each byte
-
detect and correct one bit error per byte or detect 2-bit error per byte
Optional ERR1 output signal indicates 1-bit error detection and correction
Optional ERR2 output signal indicates 2-bit error detection.
Controller can use either ERR1 or ERR2 to monitor ECC event. Unused pins (ERR1 or ERR2) can be left
floating.
Better reliability than parity code schemes which can only detect an error but not correct an error
Backward Compatible: Drop in replacement to current in industry standard devices (without ECC)

Notes:
1 Tested with the load in Figure 1.
2. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. tHZOE, tHZCS, tHZB, and tHZWE transitions are
measured when the output enters a high impedance state. Not 100% tested.
3. The internal write time is defined by the overlap of CS1# = LOW, CS2=HIGH, UB# or LB# = LOW, and WE# = LOW. All four conditions must be
in valid states to initiate a Write, but any condition can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced
to the rising or falling edge of the signal that terminates the write.
4. tPWE > tHZWE + tSD when OE# is LOW.
5. Address inputs must meet VIH and VIL SPEC during this period. Any glitch or unknown inputs are not permitted. Unknown input with standby
mode is acceptable.
6. Data retention characteristics are defined later in DATA RETENTION CHARACTERISTICS.

Notes:
1. tHZWE is based on the assumption when tSA=0nS after READ operation. Actual DOUT for tHZWE may not appear if OE# goes high before
Write Cycle. tHZOE is the time DOUT goes to High-Z after OE# goes high.
2. During this period the I/Os are in output state. Do not apply input signals.

1. If OE# is low during write cycle, tHZWE must be met in the application. Do not apply input signal during this period. Data output from the

2. Due to the restriction of note1, OE# is recommended to be HIGH during write period.
3. WE# stays LOW in this example. If WE# toggles, tPWE and tHZWE must be considered.
