Selective sense amplifier enablement

摘要

A method includes, in a data storage device, receiving a read command to read a portion of a wordline of a memory. The method also includes determining a first and a last storage element of the wordline to identify a set of storage elements. The method includes determining a first set and a second set of sense amplifiers of multiple sense amplifiers coupled to the wordline. The first set of sense amplifiers is coupled to the set of storage elements and the second set of sense amplifiers is coupled to one or more storage elements of the wordline other than the first set of storage elements. The method includes reading data by applying a read voltage to the wordline and providing a sense enable signal to each sense amplifier of the first set of sense amplifiers while each sense amplifier of the second set of sense amplifiers is disabled.

1. A method comprising:
in a data storage device including a memory and a controller, performing:
receiving a read command to read a portion of a wordline of the memory;determining a first storage element and a last storage element of the wordline to identify a set of storage elements of the wordline;determining a first set of sense amplifiers and a second set of sense amplifiers of a plurality of sense amplifiers coupled to the wordline, wherein the first set of sense amplifiers is coupled to the set of storage elements, and wherein the second set of sense amplifiers is coupled to one or more storage elements of the wordline other than the set of storage elements of the wordline; andreading data from the set of storage elements by applying a read voltage to the wordline and providing a sense enable signal to each sense amplifier of the first set of sense amplifiers while each sense amplifier of the second set of sense amplifiers is disabled.
