IS61C64B  
8K x 8 HIGH-SPEED CMOS STATIC RAM  
ISSI  
JULY 2001  
FEATURES  
DESCRIPTION  
The ISSI IS61C64B 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 pro-  
cess coupled with innovative circuit design techniques, yields  
access times as fast as 10 ns with low power consumption.  
• High-speed access time: 10, 12, and 15 ns  
• Automatic power-down when chip is  
deselected  
• CMOS low power operation  
— 450 mW (typical) operating  
— 250 µW (typical) standby  
• TTL compatible interface levels  
• Single 5V power supply  
WhenCEisHIGH(deselected),thedeviceassumesastandby  
mode at which the power dissipation can be reduced down to  
250 µW (typical) with CMOS input levels.  
Easy memory expansion is provided by using one Chip  
Enableinput, CE. TheactiveLOWWriteEnable(WE)controls  
both writing and reading of the memory.  
• Fully static operation: no clock or refresh  
required  
• Three state outputs  
The IS61C64B is packaged in the JEDEC standard 28-pin,  
300-mil DIP and SOJ, and TSOP.  
• One Chip Enables (CE) for increased speed
