Abstract
A device includes a plurality of memory cells of a memory array, a sense amplifier of the memory array, and selection logic of the memory array. The sense amplifier is configured to sense at least one data value from at least one memory cell of the plurality of memory cells. The selection logic is configured to select between causing the sense amplifier to sense the at least one data value using a first sensing delay and causing the sense amplifier to sense the at least one data value using a second sensing delay. The second sensing delay is longer than the first sensing delay.
Claims30
An apparatus comprising:
- a plurality of memory cells of a memory array;
- a sense amplifier of the memory array configured to sense at least one data value from at least one memory cell of the plurality of memory cells;
- and
- selection logic of the memory array configured to select between causing the sense amplifier to sense the at least one data value using a first sensing delay and causing the sense amplifier to sense the at least one data value using a second sensing delay, wherein the second sensing delay is longer than the first sensing delay.
A method comprising:
- in response to a read operation request, selecting a particular sensing delay from a first sensing delay and a second sensing delay, wherein the second sensing delay is longer than the first sensing delay;
- and
- sending a signal to a sense amplifier to cause the sense amplifier to sense at least one data value corresponding to the read operation request using the particular sensing delay.
An apparatus comprising:
- means for storing data;
- means for sensing at least one data value from the means for storing data;
- and
- means for selecting between causing the means for sensing at least one data value to sense the at least one data value using a first sensing delay and causing the means for sensing at least one data value to sense the at least one data value using a second sensing delay, wherein the second sensing delay is longer than the first sensing delay.
A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to:
- in response to a read operation request, initiate selecting a particular sensing delay from a first sensing delay and a second sensing delay, wherein the second sensing delay is longer than the first sensing delay;
- and
- initiate sending a signal to a sense amplifier to cause the sense amplifier to sense at least one data value corresponding to the read operation request using the particular sensing delay.
