摘要： A flash memory device capable of efficiently determining whether most significant bit (MSB) programming has been performed is provided. The flash memory device includes a cell array, a control unit, and a determination unit. The cell array includes at least one flag cell for storing information about whether MSB programming has been performed on a multi-level cell. The control unit controls a program operation, a read operation, and an erasure operation with respect to the cell array. The determination unit receives flag data stored in the flag cells, performs an OR operation and/or an AND operation on the flag data, and generates a determination signal based on a result of the OR operation and/or the AND operation, wherein the determination signal represents whether the MSB programming has been performed.

摘要： A semiconductor device includes a memory cell array and a command interface that is configured to receive a command from outside of the semiconductor memory device. The command interface is further configured to interpret the received command and to determine if the received command is a continuous operation command. The command interface outputs a command signal corresponding to the command and at least one flag signal that indicates a continuous operation section if the command is a continuous operation command. A control unit is configured to receive the command signal and the at least one flag signal output from the command interface, and to generate a pump control signal based on the received command signal and the at least one flag signal. A charge pump is configured to generate a voltage in response to the pump control signal for use in accessing the memory cell array to read right and/or erase data.

摘要： Methods of executing a multi-page copyback program in a non-volatile memory device are provided, where the non-volatile memory device includes a memory having a plurality of memory blocks. A page of data of the memory block having a first address is replaced responsive to a generated multi-page copyback program command. It is determined if the first address of the page of data is the same as a stored address of the page at which the failure was detected. The first address is incremented if it is determined that the first address and the stored address are not the same. The pages of data are replaced, the addressed are compared and the addresses are incremented until it is determined that the incremented address and the stored address are the same. Related devices and systems are also provided herein.
