The MOS technology based semiconductor ROMs are classified into _____

1.	The MOS technology based semiconductor ROMs are classified into _____ categories.(a) 2(b) 3(c) 4(d) 5This question was posed to me in a national level competition.Query is from Read Only Memory (ROM) in chapter Memory Devices of Digital Circuits
Answer» Right choice is (b) 3 For explanation: The MOS technology based SEMICONDUCTOR ROMs are CLASSIFIED into three categories: Mask ROM, PROM,& EPROM. PROM stands for PROGRAMMABLE Read Only Memory in which the ROM can be externally programmed by the user. EPROM stands for Erasable Programmable Read Only Memory, where the ROM and be CLEARED and re-programmed.
