    Abstract: A memory device is provided, including a memory array, a driver circuit, and recover circuit. The memory array includes multiple memory cells. Each memory cell is coupled to a control line, a data line, and a source line and, during a normal operation, is configured to receive first and second voltage signals. The driver circuit is configured to output at least one of the first voltage signal or the second voltage signal to the memory cells. The recover circuit is configured to output, during a recover operation, a third voltage signal, through the driver circuit to at least one of the memory cells. The third voltage signal is configured to have a first voltage level that is higher than a highest level of the first voltage signal or the second voltage signal, or lower than a lowest level of the first voltage signal or the second voltage signal.

    Abstract: Disclosed herein are related to a memory array including one-time programmable (OTP) cells. In one aspect, the memory array includes a set of OTP cells including a first subset of OTP cells connected between a first program control line and a first read control line. Each OTP cell of the first subset of OTP cells may include a programmable storage device and a switch connected between the first program control line and the first read control line. The first program control line may extend towards a first side of the memory array along a first direction, and the first read control line may extend towards a second side of the memory array facing away from the first side of the memory array.
