The MCM67A618B is a 1,179,648 bit latched address static random access memory organized as 65,536 words of 18 bits. The device integrates a 64K x 18 SRAM core with advanced peripheral circuitry consisting of address and data input latches, active low chip enable, separate upper and lower byte write strobes, and a fast output enable. This device has increased output drive capability supported by multiple power pins. Address, data in, and chip enable latches are provided. When latch enables (AL for address and chip enables and DL for data in) are high, the address, data in, and chip enable latches are in the transparent state. If latch enables are tied high the device can be used as an asynchronous SRAM. When latch enables are low the address, data in, and chip enable latches are in the latched state. This input latch simplifies read and write cycles by guaranteeing address and datain hold time in a simple fashion. DQ9 |
