Description
The IBM11D2320L is an 8MB industry standard
72-pin 4-byte single in-line memory module (SIMM).
The module is organized as a 2Mx32 high speed
memory array, and is configured as two 1Mx32
banks -each independently selectable via unique
RAS inputs. The assembly is intended for use in 16,
32 and 64 bit applications. It is manufactured with
four 1Mx16 devices, each in a 400mil TSOP or SOJ
package, and is compatible with the JEDEC 72-Pin
SIMM standard.
The IBM11D1320L is a 4MB half-populated version,
manufactured with two 1Mx16 devices in 400mil
TSOP or SOJ package .
The IBM 72-Pin SIMMs provide a high performance,
flexible 4-byte interface in a 4.25” long footprint.
