ABSTRACT:
A memory subsystem couples to a bus in common with and proceses memory requests received therefrom. The subsystem includes a single addressable memory module unit or stack having a number of word blocks of dynamic random access memory (DRAM) chips mounted on a single circuit board which connects to the remainder of the subsystem through a single word wide interface. Chip select circuits preselect a pair of blocks of RAM chips from the stack. Timing circuits generate a plurality of sequential column address pulses which are selectively applied to the preselected blocks of chips within an interval defined by a row address pulse. This results in the sequential read out of a pair of words from the preselected blocks of the single word wide module into a pair of subsystem data registers. For each memory read request, the words from each preselected pair of blocks are read out in sequence providing a double fetch capability without any loss in system performance.
