Standard 8K x 8 SRAM

ESD protection > 2000 V

change, the data outputs go High-Z

until the new read information is

available. The data outputs have no

preferred state. If the memory is

driven by CMOS levels in the active

state, and if there is no change of

the address, data input and control

signals W or G, the operating cur-

rent (at I_O= 0 mA) drops to the

value of the operating current in the

Standby mode. The Read cycle is

finished by the falling edge of E2 or

W, or by the rising edge of E1,

respectively.

Description

The U6264A is a static RAM manu-

factured using a CMOS process

technology with the following ope-

rating modes:

100 ns: 37 mA

Data retention current

at 3 V: < 10 µA (standard)

Standby current standard < 30 µA

Standby current low power

(L) < 10 µA

- Write

- Standby

- Data Retention

The memory array is based on a

6-transistor cell.

Data retention is guaranteed down

to 2 V. With the exception of E2, all
