Memory Pre-Characterization

A method of utilizing a memory device, the memory device including a plurality of pages, the method comprising:

• characterizing a transaction time for at least one page, the characterizing including
• performing a memory operation on memory cells in the at least one page, the memory operation including performing a sequence of program-validate cycles until the memory cells are in one of a programmed state or an erased state;
• measuring a time delay associated with the sequence of program-validate cycles;
• and
• storing a limit based on the measured time delay, the limit corresponding to the transaction time for the at least one page, wherein the limit corresponds to a number of program-validate cycles in the sequence;
• and
• scheduling memory operations directed to the at least one page based on the limit, such that a memory operation does not precede expiration of the limit relative to an earlier memory operation directed to the at least one page.

A memory device, comprising:

• memory;
• logic adapted to hold a value representing a programmably defined memory transaction time corresponding to a number of program-validate cycles for expected proper performance of a memory transaction in the memory;
• and
• circuitry adapted to provide an output to a memory controller that indicates whether the memory transaction has completed within the memory transaction time.

A memory device, comprising:

• memory;
• logic adapted to hold a value representing a programmably defined memory transaction time corresponding to a number of program-validate cycles for expected proper performance of a memory transaction in the memory;
• a register setting adapted to provide an output that indicates whether the memory transaction has completed within the memory transaction time;
• and
• non-volatile storage to store a number of maximum memory transaction times, each time in association with at least one respective unit of memory subdivision.
