Abstract: An apparatus may include a refresh control circuit with multiple timing circuits. The timing circuits may be used to control steal rates, e.g., the rate of refresh time slots dedicated to healing victim word lines of row hammers. The timing circuits may be controlled to allow independent adjustment of the steal rates for different victim word lines. Thus, different victim word lines may be refreshed at different rates and the different rates may be independent of one another.

Abstract: Apparatuses and methods for compensation of sense amplifiers, for example, threshold voltage compensation, are disclosed. Prime memory sense amplifiers used for accessing prime memory and redundant memory sense amplifiers used for accessing redundant memory are concurrently compensated while determining whether a memory address is remapped from prime memory to redundant memory. Following the determination, sense amplifiers (e.g., prime memory sense amplifiers and/or redundant memory sense amplifiers) that are not used for accessing the memory corresponding to the memory address are precharged.

Abstract: Apparatuses, systems and methods for dynamic timing of row pull-down operations are described herein. When a word line is accessed, the row decoder may drive that word line to an active voltage, and then to an intermediate voltage. The row decoder may maintain that word line at the intermediate voltage until another word line in the same group of word lines as the accessed word line receives an access command, at which point the first word line is driven to an inactive voltage. For example, if the word lines are grouped by bank, then after an access to a first word line, the first word line may be maintained at the intermediate voltage until a second wordline in the same bank as the first word line is accessed. This may help to mitigate the effect on other nearby word lines of driving a word line to the inactive voltage.
