DESCRIPTION
The ISSI IS61C1024 and IS61C1024L are very high-speed,
low power, 131,072-word by 8-bit CMOS static RAMs. They
are fabricated using ISSI's high-performance CMOS
technology. This highly reliable process coupled with innovative
circuit design techniques, yields higher performance and low
power consumption devices.
When CE1 is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced by using CMOS input levels.
Easy memory expansion is provided by using two Chip Enable
inputs, CE1 and CE2. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
The IS61C1024 and IS61C1024L are available in 32-pin
300-mil SOJ, and TSOP (Type I, 8x20), and sTSOP (Type I,
8 x 13.4) packages.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
