CYM1481A Description

The CYM1481A is a high-performance 16-megabit static RAM module organized as 2048K words by 8 bits. These modules are constructed from four 512K x 8 SRAMs in plastic surface-mount packages on an epoxy laminate board with pins. On-board decoding selects one of the SRAMs from the high-order address lines, keeping the remaining devices in standby mode for minimum power consumption.

An active LOW write enable signal (WE) controls the writing/reading operation of the memory. When MS and WE inputs are both LOW, data on the eight data input/output pins is written into the memory location specified on the address pins. Reading the device is accomplished by selecting the device and enabling the outputs MS and OE active LOW while WE remains inactive or HIGH. Under these conditions, the content of the location addressed by the information on the address pins is present on the eight data input/output pins.

The input/output pins remain in a high-impedance state unless the module is selected, outputs are enabled, and write enable (WE) is HIGH.
