Claim 17:
18. The method of claim 16, further comprising, after programming the PCRAM cell using the selected RESET program condition:
determining a RESET program condition operation is to be performed for the PCRAM cell;
determining whether the PCRAM cell is in a SLC mode or a MLC mode in response to determining the RESET program condition operation is to be performed for the PCRAM cell;
in response to determining that the PCRAM cell is in the SLC mode:
selecting the second RESET program condition; and
programming the PCRAM cell to a high resistance state (HRS) using the second RESET program condition; and

in response to determining that the PCRAM cell is in the MLC mode:
selecting the first RESET program condition; and
programming the PCRAM cell to an intermediate state associated with the RESET program condition operation using incremental step pulse programming initiated at the first RESET program condition.
