DESCRIPTION
The Accutek AK59256A high density memory modules is a random access memory organized in 256K x 9 bit words. The assembly consists of two 256K x 4 and one 256K x 1 DRAMs in surface mount packages mounted to the front side of a printed circuit board. The module can be configured as a leadless 30 pad SIM or a leaded 30 pin SIP. This packaging approach provides a better than 6 to 1 density increase over standard DIP packaging. The operation of the AK59256A is identical to two 256K x 4 DRAMs plus one 256K x 1 DRAM. For the lower eight bits data input is tied to data output and brought out separately for each 256K x 4 device, with mon RAS, CAS and WE...
