MEMORY DEVICE FOR PERFORMING TARGET REFRESH OPERATION, MEMORY SYSTEM AND OPERATING METHOD OF MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18527371 titled 'MEMORY DEVICE FOR PERFORMING TARGET REFRESH OPERATION, MEMORY SYSTEM AND OPERATING METHOD OF MEMORY SYSTEM
The memory system described in the patent application involves a memory controller issuing both normal refresh commands and refresh management commands, adjusting the issuance frequency based on a replacement counting value. The memory device then performs corresponding refresh operations and replaces them according to a memory information signal, counting the number of replacements to generate the replacement counting value.
- Memory controller issues normal refresh and refresh management commands

Original Abstract Submitted
A memory system includes: a memory controller configured to: issue a normal refresh command and a refresh management command, and adjust, based on a replacement counting value, an issuance frequency of at least one of the normal refresh command and the refresh management command; and a memory device configured to: perform a first refresh operation corresponding to the normal refresh h command and a second refresh operation corresponding to the refresh management command, and replace the second refresh operation with the first refresh operation according to a memory information signal, count a number of times of the replacing to generate the replacement counting value, and provide the replacement counting value.
