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 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.
The IDT7134 provides two independent ports with separate control,
address, and I/O pins that permit independent, asynchronous access
for reads or writes to any location in memory. It is the users 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 IDTs CMOS high-performance technology, these
Dual-Port typically operate on only 700mW of power. Low-power (LA)
versions offer battery backup data retention capability, with each port
typically consuming 200μW 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 Flatpack. Military grade
product is manufactured in compliance with the latest revision of MIL-
PRF-38535 QML, making it ideally suited to military temperature
applications demanding the highest level of performance and reliability.
