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.

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.

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.
