Abstract:
A memory system is provided with technology for performing temperature dependent impedance mitigation, in addition to or instead of other techniques to compensate for differences in impedance. For example, the memory system comprises a plurality of non-volatile memory cells, a first pathway connected to the plurality of non-volatile memory cells, a second pathway connected to the plurality of non-volatile memory cells, and a control circuit connected to the first pathway and the second pathway. The control circuit is configured to compensate based on temperature for a temperature dependent impedance mismatch between the first pathway and the second pathway during a memory operation on the plurality of non-volatile memory cells.
