The flash memory used for solid state drives (SSDs) and USB drives also stores bits in cells; however, when the power is turned off, the memory cells retain their content (see flash memory).

The term "NAND" is derived from the way the memory cells are organized in a series-connected structure, resembling a NAND gate. This technology is widely used in various storage devices, such as solid ...

Also, during memory tests, apart from fault detection and localization, self-repair of faulty cells through redundant cells is also implemented. It is also a challenge to test memories from the system ...
