MEMORY DEVICE, DISPLAY DEVICE EQUIPPED WITH MEMORY DEVICE, DRIVE METHOD FOR MEMORY DEVICE, AND DRIVE METHOD FOR DISPLAY DEVICE

摘要

Disclosed is a memory device that is capable of executing a first operation mode, which operates in a manner such that a dispersion level is supplied to a memory cell and a logic level is maintained in the memory cell, and that does not wastefully consume power in the first operation mode with an unnecessary power source. The memory device is equipped with a first power source (VDD) that supplies a first potential level and a second power source (VSS) that supplies a second potential level, which are used in the supply of each dispersion level; a third power source (GVDD) that supplies a potential that is higher than the maximum potential of the dispersion levels; and a fourth power source that supplies a potential that is lower than the minimum potential of the dispersion levels. When executing the first operation mode, which supplies the dispersion level to the memory cell and maintains the logic level, the memory device operates the first power source (VDD), the second power source (VSS), and the third power source (GVDD), while stopping the operation of the fourth power source.
