Semiconductor memory with divided word lines and shared sense amplifiers

摘要

A semiconductor memory device having a divided word line architecture in which each block of the memory array is divided into half-blocks and the half-blocks of each block are located on different halves of the device separated by the row decoder. A data line bussing scheme cooperates with this unique organization of the memory array to provide for sense amplifier sharing. This feature allows fewer, and larger sense amplifiers for better performance.
