8K x 8 HIGH-SPEED CMOS STATIC RAM
FEATURES
DESCRIPTION
The ISSI IS61C64AL is a very high-speed, low power,
8192-word by 8-bit static RAM. It is fabricated using ISSI's
high-performance CMOS technology. This highly reliable
processcoupledwithinnovativecircuitdesigntechniques,
yields access times as fast as 10 ns with low power
consumption.
• High-speed access time: 10 ns
• CMOS low power operation
— 1 mW (typical) CMOS standby
— 125 mW (typical) operating
• TTL compatible interface levels
• Single 5V power supply
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down to 150 µW (typical) with CMOS input levels.
• Fully static operation: no clock or refresh
required
• Lead-free available
Easy memory expansion is provided by using one Chip
Enable input, CE. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
The IS61C64AL is packaged in the JEDEC standard 28-
pin, 300-mil SOJ, and TSOP.
