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.
Themodulecanbeconfiguredasaleadless30padSIMoraleaded
30 pin SIP. This packaging approach provides a 6 to 1 density in-
crease over standard DIP packaging.
TheoperationoftheAK48256isidenticaltoeight256Kx1DRAMs.
The data input is tied to the data output and brought out separately
for each device, with common RAS, CAS and WE control. This
commonI/Ofeaturedictatestheuseofearly-writecyclestoprevent
contentionofDandQ. SincetheWrite-Enable(WE)signalmustal-
ways go low before CAS in a write cycle, Read-Write and
Read-Modify-Write operation is not possible.
