Abstract
Apparatus to store data and methods to read memory cells are disclosed. A disclosed example method involves, during a read cycle of a memory cell, applying a current across the memory cell to read a content of the memory cell. During a subsequent read cycle of the memory cell, a subsequent current is applied across the memory cell in the opposite direction to read the content of the memory cell.
Claims17
A method to read a memory cell, comprising:
- during a read cycle of the memory cell, applying a current across the memory cell to read a content of the memory cell;
- and
- during a subsequent read cycle of the memory cell, applying a subsequent current across the memory cell in a direction opposite the current to read the content of the memory cell.
An apparatus to store data, comprising:
- a memory cell;
- and
- a circuit to:
- during a read cycle of the memory cell having a dopant in a first distribution, read a content of the memory cell by applying a current across the memory cell to change the first distribution of the dopant to a second distribution, the first and second distributions of the dopant being representative of same stored information;
- and
- during a subsequent read cycle of the memory cell, read the content of the memory cell by applying a subsequent current across the memory cell to change the second distribution of the dopant to the first distribution of the dopant.
