systems which cannot tolerate wait states or are designed to

be able to externally arbitrate or withstand contention when

both sides simultaneously access the same Dual-Port RAM

location.

TheIDT7134providestwoindependentportswithseparate

control, address, and I/O pins that permit independent,

asynchronous access for reads or writes to any location in

memory. It is the user’s responsibility to ensure data integrity

when simultaneously accessing the same memory location

from both ports. An automatic power down feature, controlled

by CE, permits the on-chip circuitry of each port to enter a very

low standby power mode.

Fabricated using IDT’s CMOS high-performance

technology, these Dual-Port typically on only 500mW of

power. Low-power (LA) versions offer battery backup data

from a 2V battery.

The IDT7134 is packaged on either a sidebraze or plastic

48-pin DIP, 48-pin LCC, 52-pin PLCC and 48-pin Ceramic

Flatpack. Militarygradeproductismanufacturedincompliance

with the latest revision of MIL-STD-883, Class B, making it

ideally suited to military temperature applications demanding

the highest level of performance and reliability.

FEATURES:

• High-speed access

— Military: 25/35/45/55/70ns (max.)

— Commercial: 20/25/35/45/55/70ns (max.)

• Low-power operation

— IDT7134SA

Active: 500mW (typ.)

Standby: 5mW (typ.)

— IDT7134LA

Active: 500mW (typ.)

Standby: 1mW (typ.)

• Fully asynchronous operation from either port

• Battery backup operation—2V data retention

• TTL-compatible; single 5V (±10%) power supply

• Available in several popular hermetic and plastic packages

• Military product compliant to MIL-STD-883, Class B

• Industrialtemperaturerange(–40°Cto+85°C)isavailable,

tested to military electrical specifications

DESCRIPTION:

The IDT7134 is a high-speed 4K x 8 Dual-Port Static RAM

designed to be used in systems where on-chip hardware port

arbitration is not needed. This part lends itself to those
