A67L0618E-2.8F(2005) 数据手册 ( 数据表 ) - AMIC Technology

General Description
The AMIC Zero Bus Latency (ZeBLTM) SRAM family employs high-speed, low-power CMOS designs using an advanced CMOS process.
The A67L0618, A67L9336 SRAMs integrate a 1M X 18, 512K 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 single clock input (CLK) controls all synchronous inputs passing through the registers.
