Chapter 17
RAM, Address and Data Buses, Memory Decoding, Semiconductor Memories
OBJECTIVE
We have learnt in Chapter 13 that a memory stores the look-up tables for the bits or bytes at the outputs for each of the inputs called address inputs A ROM with 10 address input lines has 210 addresses and each address there are 8 bits in a 1 k × 8 ROM (1 k = 1024 for the purpose of memory space representation). Also a complex combinational circuit can be easily assembled by the programmable logic memories (ROM, EPROM, EEPROM or Flash or OTP). ROM is non-volatile memory (retains the bits even after power-off). We will learn an important form of semiconductor memory called RAM in this chapter. Concept of address and data buses is important for using the ...
