Abstract
A memory device includes a bit line, a source line, a program word line, a read word line, a memory cell including a program transistor and a read transistor, and a controller. The program transistor includes a gate terminal coupled to the program word line, a first terminal coupled to the source line, and a second terminal. The read transistor includes a gate terminal coupled to the read word line, a first terminal coupled to the bit line, and a second terminal coupled to the second terminal of the program transistor. The controller is configured to, in a programming operation, cause a program current to flow through the memory cell along a first current path. The controller is further configured to, in a read operation, cause a read current to flow through the memory cell along a second current path different from the first current path.
