Synchronous Dual-Port Static RAM
Features
•
True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
•
6 Flow-Through/Pipelined devices
— 16K x 16/18 organization (CY7C09269V/369V)
— 32K x 16/18 organization (CY7C09279V/379V)
— 64K x 16/18 organization (CY7C09289V/389V)
•
3 Modes
— Flow-Through
— Pipelined
— Burst
• Pipelined output mode on both ports allows fast
100-MHz operation
• 0.35-micron CMOS for optimum speed/power
•
High-speed clock to data access 6.5
/7.5
/9/12 ns
(max.)
•
3.3V low operating power
— Active = 115 mA (typical)
— Standby = 10
µA
(typical)
• Fully synchronous interface for easier operation
• Burst counters increment addresses internally
— Shorten cycle times
— Minimize bus noise
