Abstract
A non-volatile programmable circuit having programming and read bitlines, a non-volatile memory cell, and a read select transistor, and a method for its operation. The non-volatile memory cell is programmable through the programming bitline. The read select transistor is connected between the non-volatile memory cell and the read bitline. During read operation, the programming bitline is grounded and programmed information is readable onto the read bitline. During programming operation, the read bitline is grounded, and programmed information is programmable into the non-volatile memory cell for storage and retention.
