REFRESH OPERATION OF A MEMORY CELL

Abstract:

Methods, systems, and devices for a refresh operation of a memory cell are described. A memory device may include a plurality of rows of memory cells. Each row of memory cells may undergo a quantity of access operations (e.g., read operations, write operations). During a read operation, a logic state of one or more memory cells may be determined by applying a read pulse having a first polarity. Based on the one or more memory cells storing a particular logic state (e.g., a first logic state), a refresh operation may be performed. During a refresh operation, a refresh pulse having a second polarity (e.g., a different polarity than the first polarity) may be applied to the one or more memory cells.
