512K X 18, 256K X 36 LVTTL, Pipelined ZeBLTM SRAM
General Description
The AMIC Zero Bus Latency (ZeBLTM) SRAM family employs high-speed, low-power
CMOS designs using an advanced
CMOS process. The A67P9318, A67P8336 SRAMs integrate a 512K X 18, 256K X 36 SRAM core with advanced synchronous peripheral circuitry and a 2-bit burst counter. These SRAMs are optimized for 100 percent bus utilization without the insertion of any wait cycles during Write-Read alternation. The positive edge triggered singl...
