SEMICONDUCTOR STORAGE DEVICE, DESIGNING METHOD OF SEMICONDUCTOR STORAGE DEVICE, AND DESIGNING SUPPORT DEVICE FOR SEMICONDUCTOR STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To optimize an overhead due to hierarchization of compile type macros.;SOLUTION: A memory cell array is constituted which includes a first bank having a first local memory cell array and a first local sense amplifier, and a second bank having a second local memory cell array and a second local sense amplifier. Here the second bank is arranged side by side with the first bank along a global bit line direction. The first local sense amplifier preferably has performance suitably designed based upon the number of memory cells included in the first local memory cell array or the distance from the first local sense amplifier to a driver circuit. Further, the second local sense amplifier preferably has performance suitably designed based upon the number of memory cells included in the second local memory cell array or the distance from the second local sense amplifier to the driver circuit.;COPYRIGHT: (C)2012,JPO&INPIT
