Abstract
A method is provided to program a memory device through a JTAG interface of an attached component with programmable logic, wherein the memory device does not have a JTAG interface. Initially, programming hardware to provide for programming of the attached memory is downloaded into the component via the component's JTAG interface. The programmed component then becomes a serial data link between the JTAG port attached to a host programmer and a non-JTAG port attached to the memory device. The circuitry downloaded or programmed into the component controls the timing and the protocol to program the external memory.
