Automatic CE# power down
High-performance, low-power consumption, CMOS
double-poly, double-metal process
The GVT7264A16 is organized as a 65,536 x 16 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#), separate byte
enable controls (BLE# and BHE#) and output enable (OE#)
with this organization.

Packaged in 44-pin, 400-mil SOJ and 44-pin, 400-mil
TSOP
The device offers a low power standby mode when chip
is not selected. This allows system designers to meet low
standby power requirements.
