Question 4. a) Realise the following two functions of three input variables by using a ROM (Read-Only Memory). Show the connections of the ROM to implement these equations. F1(A, B, C) = Em(1,4,7) F2(A, B, C) = Em(1, 2,5, 6) [6 marks] b) The number of words and the number of bits per word can be used together to specify the size of a ROM. What size ROM is required to realise four functions of five input variables? What size ROM is required to realise eight functions of ten input variables? [2 marks] c) There are differences between a mask-programmable ROM and an EEPROM (Electrically Erasable Programmable Read-Only Memory). Which would you use for a new design that had not yet been debugged? [2 marks)
