Patent Number: RE37,427

Title: Dynamic type memory

Abstract: In a dynamic type memory, a memory cell array is divided into a plurality of sub arrays on a memory chip. Each of the sub arrays is provided with a data line formed in parallel with word lines. Data buffer and multiplexer circuits and I/O pads are arranged on one side of the memory chip in parallel with bit lines. This arrangement allows a data path to be shortened and enables data to be transferred at high speed.
