Dynamic Random Access Memory  
DESCRIPTION  
The Accutek AK5368192W high density memory module is a  
CMOS dynamic RAM organized in 8192K x 36 bit words. The mod-  
ule consists of sixteen standard 4 Meg x 4 DRAMs and eight 4 Meg  
x 1 DRAMs, each in plastic SOJ packages. The assembly has 14  
drams mounted on the front side and 10 drams mounted on the  
back side of a printed circuit board in a 72 pad leadless SIM configu-  
ration.  
+
+
This configuration allows socket-mounting of large quantities of  
memory in applications where high density and ease of inserting ad-  
ditional memory are important.

72  
The operation of the AK5368192W is identical to sixteen 4M x 4 plus  
eight 4M x 1 Drams. There are four CAS lines and four RAS lines.  
On each bank of 4M x 36, independent byte control is accomplished  
by four CAS lines. Each separate CAS line controls two 4M x 4  
Drams along with a 4M x 1 Dram with data in tied to data out to form  
a 9 bit byte. Two banks of 36 bits are controlled by the two pairs of  
RAS lines. An eighteen bit data path can be produced by connect-  
ing DQ0 to DQ18, DQ1 to DQ19, etc. and alternately strobing RAS0  
with RAS1 and RAS2 with RAS3.
