  • Publication number: 20220311335
    Abstract: A multi-mode voltage pump may be configured to select an operational mode based on a temperature of a semiconductor device. The selected mode for a range of temperature values may be determined based on process variations and operational differences caused by temperature changes. The different selected modes of operation of the multi-mode voltage pump may provide pumped voltage having different voltage magnitudes. For example, the multi-mode voltage pump may operate in a first mode that uses two stages to provide a first VPP voltage, a second mode that uses a single stage to provide a second VPP voltage, or a third mode that uses a mixture of a single stage and two stages to provide a third VPP voltage. The third VPP voltage may be between the first and second VPP voltages, with the first VPP voltage having the greatest magnitude. Control signal timing of circuitry of the multi-mode voltage pump may be based on an oscillator signal.

  • Publication number: 20220270670
    Abstract: Apparatuses, systems, and methods for refresh modes. A memory may need to perform targeted refresh operations to refresh the ‘victim’ word lines which are near to frequently accessed ‘aggressor’ word lines. To refresh the victims at a high enough rate, it may be desirable to refresh multiple victims as part of the same refresh operation. However, certain word lines (e.g., word lines in a same section or adjacent sections of the memory) cannot be refreshed together. The memory may have a section comparator, which may check stored aggressor addresses and may provide a signal if there are not two stored addresses which can be refreshed together. Based, in part, on the signal, the memory may activate one of several different refresh modes, which may control the types of refresh operation performed responsive to a refresh signal.

    Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for analog row access tracking. A plurality of unit cells are provided, each of which contains one or more analog circuits used to track accesses to a portion of the wordlines of a memory device.

A comparator circuit may determine when one or more accumulator voltages cross a threshold (e.g., a reference voltage). Responsive to the accumulator voltage crossing the threshold, an aggressor address may be loaded in a targeted refresh queue, or if the aggressor address is already in the queue, a priority flag associated with that address may be set. Aggressor addresses may be provided to have their victims refreshed in an order based on the number of set priority flags.
