Description
The IBM11S4325HP is a 16MB industry standard
72-pin 4-byte small outline dual in-line memory mod-
ule (SO DIMM). The module is organized as 4Mx32
dual bank high speed memory array that is intended
for use in 16, 32 and 64 bit applications. It is manu-
factured with eight 2Mx8 TSOP devices, each in a
400mil package. The IBM11S2325HP is an 8MB
half populated version, manufactured with four
2Mx8 TSOP devices and is organized as a single
bank 1Mx32 high speed memory array.
The use of EDO DRAMs allows for a reduction in
cycle time from 40ns (Fast Page) to 25ns (EDO,
60ns sort). The use of TSOP packages allows for
tight DIMM spacing (.3” on center). Input loading is
consistent with 4Mb-based assemblies due to the
addition of discrete capacitors maximizing compati-
bility at the system level.
These assemblies are intended for use in space
constrained and/or low power applications.
The IBM 72-Pin SO DIMMs provide a high perfor-
mance, flexible 4-byte interface in a 2.35” long foot-
print.
