The GVT72512A8 is organized as a 524,288 x 8 SRAM

using a four-transistor memory cell with a high performance,

silicon gate, low-power CMOS process. Galvantech SRAMs

are fabricated using double-layer polysilicon, double-layer

metal technology.

This device offers center power and ground pins for

improved performance and noise immunity. Static design

eliminates the need for external clocks or timing strobes. For

increased system flexibility and eliminating bus contention

problems, this device offers chip enable (CE#) and output

enable (OE#) with this organization.

Writing to these devices is accomplished when write

enable (WE#) and chip enable (CE#) inputs are both LOW.

Reading is accomplished when (CE#) and (OE#) go LOW

with (WE#) remaining HIGH. The device offers a low power

standby mode when chip is not selected. This allows system

designers to meet low standby power requirements.

High-performance, low-power consumption, CMOS
