description
The TM4100EAD9 is a dynamic random-access
memory module organized as 4 194 304 × 9 [bit
nine (D9, Q9) is generally used for parity and is
controlled by CAS9] in a 30-pin leadless single
in-line memory module (SIMM).
This module is composed of nine TMS44100DJ,
4 194 304 × 1-bit dynamic RAMs (DRAMs) each in
a 20/26-lead plastic small-outline J-lead package
(SOJ) mounted on a substrate with decoupling
capacitors.
The TM4100EAD9 is characterized for operation
from 0°C to 70°C and is available in the AD
single-sided, leadless module for use with
sockets.
