DESCRIPTION
The MH1V36CAM is an 1M word by 36-bit dynamic
RAM module and consists of 2 industry standard
1M X 16 dynamic RAMs in TSOP and 1 industry
standard 1M 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.

FUNCTION
The MH1V36CAM provide, in addition to normal read,
write, and read-modify-write operations, a number of
other functions, e.g., fast page mode, RAS-only refresh, and
delayed-write. The input conditionsfor each are shown in Table 1.
