A semiconductor device includes a plurality of memory blocks each including a plurality of memory cells, a circuit group performing a program operation, a read operation and an erase operation on a selected memory block, among the plurality of memory blocks, and a control circuit controlling the circuit group to program the memory cells of the selected memory block in a healing pattern. The healing pattern is programmed before a subsequent program operation is performed on the selected memory block. The memory cells of the healing pattern include erased memory cells and programmed memory cells arranged alternately.

Semiconductor device and method for programming healing patterns on memory blocks

A memory system and a method for operating the same are provided. The memory system includes a semiconductor memory device suitable for performing an erase operation in response to a control signal, and if an erase command is input from a host, a controller suitable for temporarily storing erase block information according the erase command, and when a program command is input after the erase command is input, transmitting the control signal according to the erase command to the semiconductor memory device.
