  • Patent number: 11049560
    Abstract: Methods, systems, and devices for a pulsed integrator and memory techniques are described. A first device may facilitate discharging a memory cell using at least one current pulse until a voltage associated with the memory cell reaches a reference voltage. The discharge time of the memory cell may be determined based at least in part on a duration of at least one current pulse. In some examples, a state of the memory cell may be determined based at least in part on a discharge time.
