    摘要: A method of programming a non-volatile memory device with memory cells formed of variable resistance elements and disposed between word lines and bit lines, includes: previously charging a selected word line and a selected bit line together with a non-selected word line and a non-selected bit line up to a certain voltage; and further charging the selected word line and the non-selected bit line up to a program voltage higher than the certain voltage and a program-block voltage, respectively, and simultaneously discharging the selected bit line.

    摘要: According to one embodiment, a nonvolatile memory device includes: a memory cell array including memory cells each having a variable resistance element for nonvolatilely storing data identified by an electrically rewritable resistance value; a first data latch storing write and erase data to be written on a given group of memory cells of the memory cell array for a write and erase operation; and a second data latch storing reference data for performing a compensation operation of the given group to compensate write and erase disturbance accompanied by the write or erase operation.

    摘要: A nonvolatile semiconductor memory device has an internal step-down power generation circuit and a memory circuit. The internal step-down power generation circuit generates a first internal power supply voltage from an external power supply voltage in an active state, and generates a second internal power supply voltage different from the first internal power supply voltage from the external power supply voltage in a standby state. The memory circuit includes a cell array containing a nonvolatile memory cell and a sense amplifier detecting data read from the cell array. The sense amplifier is supplied with a voltage generated by the internal step-down power generation circuit as an internal power supply voltage.
