Semiconductor memory device, a controller, and operating methods of the semiconductor memory device and the controller
A semiconductor memory device includes a memory cell array, a read/write circuit, control logic, and a bit flip sensor. The memory cell array includes a plurality of memory cells. The read/write circuit is configured to receive program data, and perform a program operation on selected memory cells among the plurality of memory cells, based on the program data. The bit flip sensor is configured to receive the program data from the read/write circuit, and determine whether a bit flip has occurred in the program data. The control logic is configured to control the program operation of the read/write circuit, and generate program status information, based on a determination result of the bit flip sensor.
