During programming p-n junction is _____________(a) Avalanche reverse

1.	During programming p-n junction is _____________(a) Avalanche reverse biased(b) Avalanche forward biased(c) Zener reverse biased(d) Zener reverse biasedI had been asked this question in final exam.The origin of the question is Programmable Read Only Memory topic in division Memory Devices of Digital Circuits
Answer» Right ANSWER is (a) Avalanche reverse biased Easiest EXPLANATION: The sudden heavy FLOW of electrons in the reverse direction and heat CAUSE aluminium ions to migrate. So, during PROGRAMMING p-n junction is avalanche reversed biased.
