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

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
