Semiconductor device and method of refresh thereof

摘要

The present invention relates to a semiconductor device, including memory blocks suitable for storing data, peripheral circuits suitable for refreshing the memory blocks, and a control circuit suitable for controlling the peripheral circuits to change data stored in a first memory block among the memory blocks and refresh the first memory block with changed data, and an operating method thereof.

主权项

1. A semiconductor device, comprising:
memory blocks suitable for storing data, wherein each of the memory blocks includes a normal string region in which normal data and copy data are stored and a flag string region in which flag data is stored; peripheral circuits suitable for refreshing the memory blocks; and a control circuit suitable for controlling the peripheral circuits to change data stored in a first memory block among the memory blocks and refresh the first memory block with the changed data, wherein the copy data is a duplicate of the normal data, which is stored in the first memory block, stored in a second memory block in order to refresh the first memory block, and the flag data corresponds to a refresh cycle value.
