GENERAL DESCRIPTION
The GVT73128A16 is organized as a 131,072 x 16
SRAM using a four-transistor memory cell with a high
performance, silicon gate, low-power CMOS process.
Galvantech SRAMs are fabricated using triple-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#), separate byte
enable controls (BLE# and BHE#) and output enable (OE#)
with this organization.
The device offers a low power standby mode when chip
is not selected. This allows system designers to meet low
standby power requirements.
