    Abstract: Various methods include receiving, by a controller, a temperature reading of a memory array, the temperature reading includes a temperature value; determining the temperature value is below a first threshold; in response, modifying a duration of a verify cycle of a write operation to create a modified verify cycle; then programming a first data into the memory array using the write operation that uses the modified verify cycle. Methods additionally include receiving a second temperature reading of the memory array, the second temperature reading includes a second temperature value; determining the second temperature value is below a second threshold, in response, decreasing the duration of a verify cycle of a verify cycle to create a second verify cycle, where the second verify cycle is shorter than the modified verify cycle; and then programming a second data into the memory array using the write operation that uses the second verify cycle.

    Abstract: A circuit includes a detection circuit configured to determine a capacitance delay (RC-delay) in an initial stage of a read or program operation and to adjust timing for detecting data in a subsequent stage, or portion of a stage, of the same read or programing operation. In particular, during a program operation a detection circuit may be configured to detect a pre-charge time for a bit line and adjust a timing of subsequent verify stages of the bit line during the same program operation based on the detected pre-charge time. Additionally, a word line circuit may be configured to detect a pre-charge time for a word line during an initial stage of a read operation and adjust read timing for a subsequent portion of the same read stage, or subsequent read stage of the read operation based on the detected word line pre-charge time.
