FAST PAGE MODE 150994944-BIT ( 4194304-WORD BY 36-BIT ) DYNAMIC RAM
DESCRIPTION
The MH4V36AM is an 4M word by 36-bit dynamic
RAM module and consists of 2 industry standard
4M X 16 dynamic RAMs in TSOP and 1 industry
standard 4M X 4(4CAS) dynamic RAMs in TSOP.
The ICs are mounted on both sides of one small
ceracom PC board with flash gold plating and form a
convenient 68-pin package.
