  • Publication number: 20240062820
    Abstract: A system includes a memory device and a processing device coupled to the memory device. The processing device is to perform operations including determining whether one or more memory access operations performed on a range of consecutive wordlines of a memory device satisfy one or more criteria. The operations further include, responsive to determining that the one or more memory access operations satisfy the one or more criteria, causing a memory management operation to be performed at each wordline of the range of consecutive wordlines of the memory device.

  • Patent number: 11817151
    Abstract: A system includes a memory device and a processing device coupled to the memory device. The processing device is to perform operations including maintaining a counter to track a number of memory access operations performed on a range of consecutive wordlines in a block of the memory device. The operations further include determining that the number of memory access operations performed on the range of consecutive wordlines satisfies a threshold criterion. The operations further include, responsive to the number of memory access operations performed on the range of consecutive wordlines satisfying the threshold criterion, causing a memory management operation to be performed at each wordline of the range of consecutive wordlines in the block of the memory device.

  • Patent number: 11342024
    Abstract: A data structure including two or more entries is maintained, where each entry corresponds to a range of consecutive wordlines in a block of a memory device. Each entry includes an operation counter to track a number of memory access operations performed on the range of consecutive wordlines in the block of the memory device. An indication of a memory access operation pertaining to the particular wordline is received. In response to the indication of the memory access operation pertaining to the particular wordline, a determination is made whether the particular wordline is within any range of consecutive wordlines that has a corresponding entry in the data structure. In response to the particular wordline being outside of any range of consecutive wordlines that has a corresponding entry in the data structure, a new entry for a new range of consecutive wordlines that includes the particular wordline is created.

  • Patent number: 6307797
    Abstract: A device for reading a memory including precharging circuits for precharging the inputs of a differential amplifier to a precharging voltage. The precharging voltage may be at an intermediate voltage level between a precharging voltage level of the bit lines and the voltage level of the logic supply voltage. This provides for a very fast build-up, during a following evaluation phase, of the output of the amplifier in a state corresponding to that of the cell being read. An internal detection circuit may also be included to detect an end of the precharging to stop the precharging circuit and activate the read current generator for the evaluation phase.
