Abstract

The subject technology performs the following in a storage system including memory dies, where each memory die includes its own temperature sensor. The subject technology determines a temperature of each of the memory dies based on a temperature reading from each memory die's temperature sensor. The subject technology determines whether data is hot data or cold data, where hot data is more likely to be changed after it is written than cold data. In response to determining that the data is hot data, the subject technology stores the data in a memory die with a relatively higher temperature than another one of the memory dies. Further, in response to determining that the data is cold data, the subject technology stores the data in a memory die with a relatively cooler temperature than another one of the memory dies.
