Read model of memory cells using information generated during read operations

Abstract

A memory sub-system configured to generate or update a model for reading memory cells in a memory device. For example, in response to a processing device of a memory sub-system transmitting to a memory device read commands that are configured to instruct the memory device to retrieve data from a group of memory cells formed on an integrated circuit die in the memory device, the memory device may measure signal and noise characteristics of the group of memory cells during execution of the read commands. Based on the signal and noise characteristics the memory sub-system can generate or update, measured during the execution of the read commands a model of changes relevant to reading data from the group of memory cells. The changes can be a result of damage, charge loss, read disturb, cross-temperature effect, etc.
