US 10,854,274 B1 · Apparatuses and methods for dynamic timing of row pull down operations

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.

Dependent claims

An apparatus comprising:

a first plurality of word lines including a first word line associated with a first row address;
and
a row decoder configured to provide a first voltage and then a second voltage to a first wordline responsive to receiving the first row address and configured to provide a third voltage to the first word line responsive to receiving a row address associated with one of the first plurality of word lines different from the first word line, wherein the first voltage is greater than the third voltage and wherein the second voltage is between the first voltage and the third voltage.

Dependencies are inferred from the claim text.
