Abstract: Techniques are disclosed relating to level-shifting circuitry and time borrowing across voltage domains. In some embodiments, sense amplifier circuitry generates, based on an input signal at a first voltage level, an output signal at a second, different voltage level. Pulse circuitry may generate a pulse signal in response to an active clock edge of a clock signal that is input to the sense amplifier circuitry. Initial resolution circuitry may drive the output signal of the sense amplifier circuitry to match the value of the input signal during the pulse signal. Secondary resolution circuitry may maintain a current value of the output signal after expiration of the pulse signal. This may allow the input signal to change during the pulse, e.g., to enable time borrowing by upstream circuitry.

Abstract: The address of victim rows may be determined based on rows that are accessed in a memory. The victim addresses may be stored and associated with a count for every time a victim row is “victimized.” When the count for a victim row reaches a threshold, the victim row may be refreshed to preserve data stored in the row. After the victim row has been refreshed, the count may be reset. When a victim row is accessed, the count may also be reset. The counts may be adjusted for closer victim rows (e.g., +/?1) at a faster rate than counts for more distant victim rows (e.g., +/?2). This may cause closer victim rows to be refreshed at a higher rate than more distant victim rows.
