M372F320(8)0DJ4-C EDO Mode
32M x 72 DRAM DIMM with ECC Using 16Mx4, 4K & 8K Refresh, 3.3V

The Samsung M372F320(8)0DJ4-C is a 32Mx72bits Dynamic
RAM high density memory module. The Samsung
M372F320(8)0DJ4-C consists of thirty-six CMOS 16Mx4bits
DRAMs in SOJ 400mil packages and two 16 bits driver IC in
TSSOP package mounted on a 168-pin glass-epoxy sub-
strate. A 0.1 or 0.22uF decoupling capacitor is mounted on
the printed circuit board for each DRAM. The
M372F320(8)0DJ4-C is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.

GENERAL DESCRIPTION

PD Note :PD & ID Terminals must each be pulled up through a register to V

at the next higher

level assembly. PDs will be either open (NC) or driven to V

via on-board buffer circuits.

ID Note : IDs will be either open (NC) or connected directly to V

without a buffer.

NOTES

An initial pause of 200us is required after power-up followed
by any 8 RAS-only or CAS-before-RAS refresh cycles before
proper device operation is achieved.

Input voltage levels are V

. V

(min) and V

(max) are ref-

erence levels for measuring timing of input signals. Transi-
tion times are measured between V

(min) and V

(max) and

are assumed to be 5ns for all inputs.

Measured with a load equivalent to 1 TTL loads and 100pF.

Operation within the

RCD

(max) limit insures that

RAC

(max)

can be met.

RCD

(max) is specified as a reference point only.

RCD

is greater than the specified

RCD

(max) limit, then

access time is controlled exclusively by

This parameter defines the time at which the output achieves
the open circuit condition and is not referenced to V

WCS

CWD

AWD

and

CPWD

are not restrictive operat-

ing parameter. They are included in the data sheet as electri-

cal characteristics only. If

WCS

early write cycle and the data out pin will remain high imped-

ance for the duration of the cycle. If

RWD

CWD

AWD

(min) and

CPWD

(min).

The cycle is a read-modify-write cycle and the data out will
contain data read from the selected cell. If neither of the
above sets of conditions is satisfied, the condition of data
out(at access time) is indeterminate.

Either

RCH

RRH

must be satisfied for a read cycle.

These parameters are referenced to the CAS leading edge in
early write cycles.

Operation within the

RAD

(max) limit insures that

RAC

(max)

can be met.

RAD

(max) is specified as reference point only. If

RAD

is greater than the specified

RAD

(max) limit, then

access time is controlled by

If RAS goes high before CAS high going, the open circuit
condition of the output is achieved by CAS high going. If CAS
goes high before RAS high going , the open circuit condition
of the output is achieved by RAS going.
