ACCESS SCHEMES FOR PROTECTING STORED DATA IN A MEMORY DEVICE

Abstract:

Methods, systems, and devices for protecting stored data in a memory device are described. In one example, a memory device may include a set of memory cells coupled with a digit line and a plate line. A method of operating the memory device may include performing an access operation on a selected memory cell of the set of memory cells, and performing an equalization operation on a non-selected memory cell of the plurality of memory cells based on performing the access operation. The equalization operation may include applying an equal voltage to opposite terminals of the non-selected memory cell via the digit line and the plate line, which may allow built-up charge, such as leakage charge resulting from the access operation, to dissipate. Such an equalization operation may reduce a likelihood of memory loss in non-selected memory cells after access operations.
