摘要: A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to determine that a power loss event has occurred, determine that one or more blocks are in an erased state, examine a block of the one or more blocks to determine whether the block is a SLC erased block or a TLC erased block, and place the block in a SLC pre-erase heap if the block is the SLC erased block or in a TLC pre-erase heap if the block is the TLC erased block. The controller is further configured to determine a first bit count of page0 for a SLC voltage for the block, determine a second bit count of page1 for a TLC voltage for the block, and classify the block as either a SLC erased block or a TLC erased block.

摘要: A memory device includes a main memory, a first sub-memory and a controller. When the first sub-memory is erased, the first sub-memory generates a first erase completion signal. The controller receives an erase signal to erase the main memory. The controller performs an erase operation on the main memory according to the erase signal and the first erase completion signal.

摘要: A method of erasing memory cells in a memory device is provided. The method includes grouping a plurality of word lines into a first group, which does not include edge word lines, and a second group, which does include edge word lines. An erase operation is performed on the memory cells of the first and second groups until erase-verify of the memory cells of the first group passes. It is then determined if further erase of the memory cells of the second group is necessary. In response to it being determined that the additional erase operation is necessary, an additional erase operation is performed on at least some of the memory cells of the second group until erase-verify of the memory cells of the second group passes.

摘要: A nonvolatile memory device includes a memory cell array having cell strings that each includes memory cells stacked on a substrate in a direction perpendicular to the substrate. A row decoder is connected with the memory cells through word lines. The row decoder applies a setting voltage to at least one word line of the word lines and floats the at least one word line during a floating time. A page buffer circuit is connected with the cell strings through bit lines. The page buffer senses voltage changes of the bit lines after the at least one word line is floated during the floating time and outputs a page buffer signal as a sensing result. A counter counts a number of off-cells in response to the page buffer signal. A detecting circuit outputs a detection signal associated with a defect cell based on the number of off-cells.
