DESCRIPTION:
The IDT7M1001/IDT7M1003 is a 128K x 8/64K x 8 high-
speed CMOS Dual-Port Static RAM module constructed on a
multilayer ceramic substrate using eight IDT7006 (16K x 8)
Dual-Port RAMs and two IDT FCT138 decoders or depopu-
lated using only four IDT7006s and two decoders.
• Fully asynchronous read/write operation from either port
• Full on-chip hardware support of semaphore signaling
between ports
• Surface mounted LCC (leadless chip carriers) compo-
nents on a 64-pin sidebraze DIP (Dual In-line Package)
• Multiple Vcc and GND pins for maximum noise immunity
• Single 5V (±10%) power supply
• Input/outputs directly TTL-compatible
This moduleprovidestwoindependentportswithseparate
control, address, and I/O pins that permit independent and
asynchronous access for reads or writes to any location in
memory. System performance is enhanced by facilitating
port-to-port communication via semaphore (SEM) “hand-
shake” signaling. The IDT7M1001/1003 module is designed
to be used as stand-alone Dual-Port RAM where on-chip
hardware port arbitration is not needed. It is the users re-
sponsibility to ensure data integrity when simultaneously
accessing the same memory location from both ports.
The IDT7M1001/1003 module is packaged on a multilayer
co-fired ceramic 64-pin DIP (Dual In-line Package) with di-
mensions of only 3.2" x 0.62" x 0.38". Maximum access times
as fast as 35ns over the commercial temperature range are
available.
All inputs and outputs of the IDT7M1001/1003 are TTL-
compatible and operate from a single 5V supply. Fully asyn-
chronouscircuitryisused, requiringnoclocksorrefreshingfor
operation of the module.
All IDT military module semiconductor components are
manufacured in compliance with the latest revision of MIL-
STD-883, Class B, making them ideally suited to applications
demanding the highest level of performance and reliability.
