Low profile 72-pin ZIP (Zig-zag In-line vertical  
Package) or 72-pin SIMM (Single In-line Memory

tion allows 72 pins to be placed on a package 3.95" 2  
long and 0.250" wide. At only 0.600" high, this low-  
profile package is ideal for systems with minimum  
board spacing. The SIMM configuration allows use of

provide maximum immunity from noise.  
Four identification pins (PD0, PD1, PD2, PD3) are pro-  
vided for applications in which different density  
versions of the module are used. In this way, the tar-  
get system can read the respective levels of PD0, PD1,  
PD2, PD3 to determine a 512K depth.  
Description  
5
The PDM4M4110 is a 512K x 32 static RAM module  
constructed on an epoxy laminate (FR-4) substrate  
using four (4) 512K x 8 static RAMs in plastic SOJ  
packages. Availability of four chip select lines pro-  
vides byte access. The PDM4M4110 is available with  
access times as fast as 15 ns with minimal power  
consumption.
