REFRESHING DATA STORED AT A MEMORY COMPONENT BASED ON A MEMORY COMPONENT CHARACTERISTIC COMPONENT

Abstract:

One or more write operations are performed on a memory component. First data stored at the memory component is read. A determination is made as to whether an error rate associated with the first data stored at the memory component exceeds an error rate threshold. If the error rate exceeds the error rate threshold, a threshold value is adjusted. A determination is made as to whether a number of the plurality of write operations performed on the memory component since performance of a refresh operation on the memory component exceeds the threshold value. In response to determining that the number of write operations performed on the memory component exceeds the threshold value, a memory cell of the memory component is identified based on the plurality of write operations. Second data stored at memory cells of the memory component that are proximate to the identified memory cell is refreshed.
