    摘要: A memory device includes pages, each being composed of a plurality of memory cells arrayed on a substrate in row form. The memory device controls voltages to be applied to a first gate conductor layer, a second gate conductor layer, a first impurity region, and a second impurity region of each of the memory cells included in the pages to perform a page write operation of holding a hole group formed by an impact ionization phenomenon or a gate induced drain leakage current in a channel semiconductor layer, and controls voltages to be applied to the first gate conductor layer, the second gate conductor layer, the third gate conductor layer, the fourth gate conductor layer, the first impurity region, and the second impurity region to perform a page erase operation of removing the hole group out of the channel semiconductor layer. The first impurity layer of each of the memory cells is connected to a source line, the second impurity region is connected to a bit line, one of the first gate conductor layer and the second gate conductor layer is connected to a word line, and the other is connected to a first driving control line. The bit line is connected to a sense amplifier circuit via a switching circuit. When in a page read operation, the memory device reads page data in a memory cell group selected by the word line to the bit line, and performs charge sharing between the bit line and a charge sharing node of the switching circuit opposite to the bit line to accelerate a read determination by the sense amplifier circuit.

    摘要: A memory device includes a memory cell array, a row select circuit, a refresh controller and a memory control logic. The memory cell array includes memory cells arranged in rows and columns. The row select circuit is connected to the rows. The refresh controller controls the row select circuit to apply a refresh operating voltage to one or more rows. The memory control logic decodes a command received from a memory controller and outputs a refresh command and external refresh address information. The refresh controller controls the row select circuit to perform one of an external refresh operation and an internal refresh operation, based on the refresh command that is output from the memory controller and based on whether a first row-hammering row address of the internal refresh operation is identical with a second row-hammering row address of the external refresh operation.

    摘要: A memory system includes: a first nonvolatile memory; a second volatile memory; a controller; a power control circuit configured to perform control such that a first voltage is applied to the first memory, the second memory, and the controller based on first power supplied from an external power supply; and a power storage device configured to supply second power to the power control circuit while the first power from the external power supply is interrupted. While the first power supplied from outside is interrupted, the power control circuit applies a second voltage based on the second power supplied from the power storage device to the first memory, the second memory, and the controller. The power control circuit stops the application of the second voltage to the second memory after the data is read from the second memory and before the data is written into the first memory.
