Abstract
An apparatus and method whereby a static column mode DRAM can access a unique data bit located anywhere within the array chip and sustain a continuous transfer of requested bits in a contiguous group of bits (i.e. block). Steering of the data in a prescribed order is accomplished via a special steering and gating network. A control line, toggle, is used on both rising and falling edges to produce this gapless transfer.
