    摘要: Memory devices and/or methods that may estimate characteristics of multi-bit cell are provided. A memory device may include: a multi-bit cell array; a monitoring unit to extract a threshold voltage change over time value for reference threshold voltage states selected from a plurality of threshold voltage states corresponding to data stored in the multi-bit cell array; and an estimation unit to estimate a threshold voltage change over time values for the plurality of threshold voltage states based on the extracted threshold voltage change. Through this, it is possible to monitor a change over time of threshold voltages of a memory cell.

    摘要: Nonvolatile memory devices include support memory cell recovery during operations to erase blocks of nonvolatile (e.g., flash) memory cells. A nonvolatile memory system includes a flash memory device and a memory controller electrically coupled to the flash memory device. The memory controller is configured to control memory cell recovery operations within the flash memory device by issuing a first instruction(s) to the flash memory device that causes erased memory cells in the block of memory to become at least partially programmed memory cells and then issuing a second instruction(s) to the flash memory device that causes the at least partially programmed memory cells become fully erased.

    摘要: An error control coding (ECC) circuit includes a first decoder, a second decoder, and a controller. The first decoder receives encoded data comprising a first parity and a second parity. The first decoder decodes the encoded data to a first code by using the first parity. The second decoder is connected to the first decoder. The second decoder is configured to decode the encoded data when the first decoder is deactivated and decode the first code using the second parity when the first decoder is deactivated. The controller transmits a control signal to the first decoder and the second decoder to control the first decoder and the second decoder.
