Nonvolatile semiconductor storage device, and liquid crystal display device including the same

Abstract

A nonvolatile semiconductor storage device including: a plurality of memory cell unit groups each comprising one or more NAND nonvolatile memory cell units each comprising at least one memory cell having a control gate, a first selection transistor having a first selection gate, and a second selection transistor having a second selection gate, the memory cell unit groups each further comprising a control gate line connected to the control gate, a first selection gate line connected to the first selection gate, and a second selection gate line connected to the second selection gate; a common control gate line connected commonly to the control gate lines of different ones of the memory cell unit groups; a first common selection gate line connected commonly to the first selection gate lines of different ones of the memory cell unit groups; and a second common selection gate line connected commonly to the second selection gate lines of different ones of the memory cell unit groups; wherein the memory cells in the respective memory cell unit groups are each uniquely selected on the basis of a combination of the common control gate line and the first and second common selection gate lines.
