IS61C1024 IS61C1024L
128K x 8 HIGH-SPEED CMOS STATIC RAM

ISSI

MAY 1999
• High-speed access time 12, 15, 20, 25 ns
• Low active power 600 mW typical
• Low standby power 500 µW typical CMOS
standby
• Output Enable OE and two Chip Enable CE1 and CE2 inputs for ease in applications
• Fully static operation no clock or refresh required
• TTL compatible inputs and outputs
• Single 5V ±10% power supply
• Low power version available IS61C1024L
• Commercial and industrial temperature ranges
available

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 packages.
