Semiconductor memory device, memory system including the same and operating method thereof

摘要

A semiconductor memory device includes a program and read unit suitable for programming program data in a memory cell array and for reading read data stored in the memory cell array, and a control unit suitable for generating a control signal for controlling the program and read unit in response to a command input from the outside of the semiconductor memory device, in which the control unit controls the program and read unit to read the read data in a state of storing a first bit data of the program data when a read command is input while programming the program data.

主权项

1. A semiconductor memory device, comprising:
a program and read unit temporarily storing program data including a first bit data and a second bit data, programming the program data temporarily stored in a memory cell array, or reading data stored in the memory cell array; and a control unit suitable for generating a control signal for controlling the program and read unit in response to a command input from the outside of the semiconductor memory device, wherein the control unit controls the program and read unit to stop programming the program data when a read command is input while programming the program data, and perform a read operation while maintaining the first bit data stored when programming the program data.
