Fusing process is ___________(a) Reversible(b) Irreversible(c) Synchronous(d) AsynchronousI got this question in exam.Origin of the question is Programmable Read Only Memory in portion Memory Devices of Digital Circuits

Answer» RIGHT OPTION is (b) Irreversible

Explanation: SINCE, any program cannot be reprogrammed in a PROM, so this process is irreversible as PROMS are programmed using the Fusing process. Fusing is a process by which programs are burnout to the diode/transistors and it can not be reprogrammed if any error OCCURS.
