Classification: CPC G | IPC G

Claim 19:
20. A method for configuring a phase-change random-access memory (PCRAM) cell, comprising:
receiving a configuration change command associated with the PCRAM cell, wherein the configuration change command is generated based at least in part on an error tolerance for a neural network layer;
determining a type of the received configuration change command;
selecting, based at least in part on the determined type of the received configuration change command, a RESET verification condition from a plurality of stored RESET verification conditions;
programming the PCRAM cell using a RESET pulse;
determining a PCRAM cell condition in response to programming the PCRAM cell using the RESET pulse;
determining whether the determined PCRAM cell condition meets the selected RESET verification condition;
modifying the RESET pulse to increase one or both of its current amplitude and its pulse width in response to determining the determined PCRAM cell condition does not meet the selected RESET verification condition; and
programming the PCRAM cell using the modified RESET pulse.
