Memory devices configured to apply different weights to different strings of memory cells coupled to a data line and methods

摘要

Memory devices and methods are disclosed. One such method compares input data to stored data in a memory device and includes applying a first weight factor to a first string of memory cells coupled to a data line, where a first bit of the stored data is stored in the first string of memory cells; applying a second weight factor to a second string of memory cells coupled to the data line, where a second bit of the stored data is stored in the second string of memory cells; comparing a first bit of input data to the first bit of the stored data while the first weight factor is applied to the first string of memory cells; and comparing a second bit of the input data to the second bit of the stored data while the second weight factor is applied to the second string of memory cells.

主权项

1. A method of comparing input data to stored data in a memory device, comprising:
applying a first weight factor to a first string of memory cells coupled to a data line, wherein a first bit of the stored data is stored in the first string of memory cells; applying a second weight factor to a second string of memory cells coupled to the data line, wherein a second bit of the stored data is stored in the second string of memory cells; comparing a first bit of input data to the first bit of the stored data while the first weight factor is applied to the first string of memory cells; and comparing a second bit of the input data to the second bit of the stored data while the second weight factor is applied to the second string of memory cells.
