General Description
The A615308 is a high-speed, low-power 262,144-bit
static random access memory organized as 32,768
words by 8 bits and operates on a single 5V power
supply. It is built using high performance CMOS process.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
Minimum standby power is drawn by this device when
CE is at a high level, independent of the other input
levels.
Data retention is guaranteed at a power supply voltage
as low as 2V.

WE is high for Read Cycle.
Device is continuously enabled, CE = VIL.
Address valid prior to or coincident with CE transition low.
OE = VIL.
Transition is measured ±200mV from steady state. This parameter is sampled and not 100% tested.

tAS is measured from the address valid to the beginning of Write.
A Write occurs during the overlap (tWP) of a low CE and a low WE .
tWR is measured from the earliest of CE or WE going high to the end of the Write cycle
If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs
remain in a high impedance state.
5. tCW is measured from the later of CE going low to the end of Write.
6. OE is continuously low. ( OE = VIL)
7. Transition is measured ±200mV from steady state. This parameter is sampled and not 100% tested.
