Description
The GMM27333230ATG is a 32M x 72bits
Synchronous Dynamic RAM MODULE
which is assembled 18 pieces of 32M x 4bits
Synchronous DRAMs in 54 pin TSOP II, 2
pieces of 16 bits Register in 48 pin TSSOP,
one clock distribution PLL in 24 pin SOP and
one 2048 bit EEPROM in 8 pin TSSOP
package mounted on a 168 pin printed circuit
board with decoupling capacitors. The
GMM27333230ATG is optimized for
application to the systems which are required
high density and large capacity such as main
memory of the computers and an image
memory systems, and to the others which are
requested compact size.
The GMM27333230ATG provides common
data inputs and outputs.
