摘要: A memory device includes a memory cell array including M memory cells connected to one bit line and configured to distributively store N-bit data, where N is a natural number and M is a natural number of 2 or more and N or less, the M memory cells including a first memory cell and a second memory cell having different sensing margins, and a memory controller including a page buffer, the memory controller configured to distributively store the N-bit data in the M memory cells and to sequentially read data stored in the M memory cells to obtain the N-bit data, and an operation logic configured to execute an operation using the N-bit data, the memory controller configured to provide different reading voltages to the first memory cell and the second memory cell.

摘要: A memory device includes a memory cell array including a plurality of memory cells; a voltage generator configured to generate voltages used for a program operation and a verify operation for the memory cells; and control logic configured to perform a plurality of program loops while writing data to the memory cell array, such that first to N-th (e.g., N>=1) program loops including a program operation and a verify operation are performed and at least two program loops in which the verify operation is skipped are performed when a pass/fail determination of the program operation in the N-th program loop indicates a pass.
