PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The MH1M365CXJ/CNXJ is 1048576-word x 36-bits dynamic
RAM. This consists of two industry standard 1M x 16 dynamic
RAMs in SOJ and one industry 1M x 4 dyanmic RAMs in SOJ.
The mounting of SOJ on a single in-line package provides any
application where high densities and large quantities of memory
are required. This is a socket-type memory module,suitable for
easy interchange or addition of modules.

Note 6: An initial pause of 500µs is required after power-up followed by a minimum of eight initialization cycles (any combination of cycles
containing a RAS clock such as RAS-Only refresh).
Note the RAS may be cycled during the initial pause . And any 8 RAS or RAS/CAS cycles are required after prolonged periods
(greater than 16.4 ms) of RAS inactivity before proper device operation is achieved.
7: Measured with a load circuit equivalent to VOH=2.4V(IOH=-5mA) / VOL=0.4V(IOL=-4.2mA) load 100pF.
The reference levels for measuring of output signal are 2.0V(VOH) and 0.8V(VOL).
