Dynamic Random Access Memory

DESCRIPTION

Front View

30-Pin SIM

The Accutek AK584096 high density memory module is CMOS

DRAM organized in 4 Meg x 8 bit words. The assembly consists of

eight standard 4 Meg x 1 DRAMs in plastic SOJ packages mounted

on the front side of a printed circuit board. The module can be con-

figured as a leadless 30 pad SIM or a leaded 30 pin SIP. The mod-

ule is only 0.800 inch high (same height as a standard 1 Meg

module) making it ideally suited for applications with low height

restrictions.

30-Pin SIP

The operation of the AK584096 is identical to eight 4 Meg x 1

DRAMs. The data input is tied to the data output and brought out

separately for each device, with common RAS, CAS and WE con-

trol. This common I/O feature dictates the use of early-write cycles

to prevent contention of D and Q. Since the Write-Enable (WE) sig-

nal must always go low before CAS in a write cycle, Read-Write and

Read-Modify-Write operation is not possible.

· Operating free air temperature 0⁰C to 70⁰C

· Upward compatible with AK5816384

FEATURES

· 4,194,304 x 8 bit organization

· Optional 30 Pad leadless SIM (Single In-Line Module) or 30

Pin leaded SIP (Single In-Line Package)

· Downward compatible with AK58256 and AK581024

· JEDEC standard pinout

· Each device has common D and Q lines with common RAS,

CAS and WE control
