APPARATUSES AND METHODS FOR PERFORMING AN EXCLUSIVE OR OPERATION USING SENSING CIRCUITRY

摘要

The present disclosure includes apparatuses and methods related to determining an XOR value in memory. An example method can include performing a NAND operation on a data value stored in a first memory cell and a data value stored in a second memory cell. The method can include performing an OR operation on the data values stored in the first and second memory cells. The method can include performing an AND operation on the result of the NAND operation and a result of the OR operation without transferring data from the memory array via an input/output (I/O) line.

1. A method, comprising:
determining, using sensing circuitry coupled to a pair of complementary sense lines of an array of memory cells, an exclusive OR (XOR) value of data stored in a number of memory cells coupled to a first sense line of the pair without transferring the data from the array using an input/output line, wherein determining the XOR value comprises: performing an AND operation on:
a resultant value of a NAND operation performed on a first data value stored in a first memory cell coupled to the first sense line and a second data value stored in a second memory cell coupled to the first sense line; anda resultant value of an OR operation performed on the first data value and the second data value.
