Accutek Microcircuit Corporation DESCRIPTION The Accutek AK48256 high density memory modules is a random access memory organized in 256K x 8 bit words. The assembly consists of eight standard 256K x 1 DRAMs in plastic leaded chip carriers (PLCC) mounted on 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 6 to 1 density increase over standard DIP packaging. The operation of the AK48256 is identical to eight 256K 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 control. This common I/O feature dictates the use of early-write cycles to prevent contention of D and Q. Since the Write-Enable (WE) signal must always go low before CAS in a write cycle, Read-Write and Read-Modify-Write operation is not possible.
