DESCRIPTION
The ISSI IS61C6416AL, IS62C6416AL, IS64C6416AL and
IS65C6416AL are high-speed, 1,048,576-bit static RAMs
organized as 65,536 words by 16 bits. They are fabricated
using ISSI's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design techniques, yields access times as fast as 12 ns with low power
consumption.
When CE is HIGH (deselected), 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, CE and OE. 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.
The IS61C6416AL, IS62C6416AL, IS64C6416AL and
IS65C6416AL are packaged in the JEDEC standard 44-pin
400-mil SOJ and 44-pin TSOP (Type II).

2. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE LOW and UB or LB, and WE LOW. All signals must be in valid states to
initiate a Write, but any one 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.
