MARKING

The SMJ44400 is offered in a 400-mil, 20-pin ceramic side-

brazed dual-in-line package (JD sufﬁx) and a 20-pin ceramic

ﬂatpack (HR sufﬁx) that are characterized for operation from

-55°C to +125°C.

OPERATION

Enhanced Page Mode

No. 308

Enhanced page-mode operation allows faster memory ac-

cess by keeping the same row address while selecting random

column addresses. The time for row-address setup and hold

and address multiplex is eliminated. The maximum number of

columns that can be accessed is determined by the maximum

RAS\ low time and the CAS\ page cycle time used. With

minimum CAS\ page cycle time, all 1024 columns speciﬁed

by column addresses A0 through A9 can be accessed without

intervening RAS\ cycles.

• Operating Temperature Ranges

GENERAL DESCRIPTION

The SMJ44400 is a series of 4,194,304-bit dynamic

random-access memories (DRAMs), organized as 1,048,576

words of four bits each. This series employs state-of-the-art

technology for high performance, reliability, and low-power

operation.

Unlike conventional page-mode DRAMs, the col-

umn address buffers in this device are activated on the

(continued)

The SMJ44400 features maximum row access times of 80ns,

100ns, and 120ns. Maximum power dissipation is as low as

360mW operating and 22mW standby.

All inputs and outputs, including clocks, are compatible with

Series 54 TTL. All addressses and data-in lines are latched on-

chip to simplify system design. Data out is unlatched to allow

greater system ﬂexibility.
