As shown in the block diagram below, a ROM has k address input lines to select one of 2 k = m words of memory, and n input lines, one for each bit of the word. An integrated circuit ROM may also have one or more enable inputs for expanding a number of packages into a ROM with larger capacity.. An integrated circuit ROM may also have one or.

Read-only memory (ROM) is similar in design to static or dynamic RAM circuits, except that the "latching" mechanism is made for one-time (or limited) operation. The simplest type of ROM is that which uses tiny "fuses" which can be selectively blown or left alone to represent the two binary states. Obviously, once one of the little fuses.

The read only memory cell usually consists of a single transistor (ROM and EPROM cells consist of one transistor, EEPROM cells consist of one, one-and-a-half, or two transis-tors). The threshold voltage of the transistor determines whether it is a "1" or "0.". During the read cycle, a voltage is placed on the gate of the cell.

Introduction A Read-Only-Memory (ROM) is a large scale integration (LSI) combinational circuit. ROM circuits can store binary words of a fixed length in each "cell". Each cell has an associated binary number usually referred to as "address". The number of cells is determined by the address' number of bits.

The ROM circuit shown in figure 9.15, is actually a combination of two logic circuits (an encoder and a decoder, i.e. ROM is fabricated by means of mounting an encoder and thereafter fitting a decoder), where in the mounted decoder (binary to the decimal converter) receives address consisting of 8 - bits and selects 2 n memory locations on.
Instruction ROM
Circuit Description. This applet demonstrates the internal structure of a read-only memory or ROM . A rather small memory size of 16 words of 8 bits each is used. From left to right, the circuit consists of three stages. The first stage, usually called address-decoder in memory circuits, is a standard demultiplexer.

Types of Read-Only Memory (ROM) 1. Simple ROM and Masked ROM. Earlier, simple ROMs were made using the diodes. A simple Diode ROM consists of only diodes and a decoder as shown in below fig. A 2:4 decoder is used to decode address lines A0 and A1 and it selects one of the four rows. Since the nature of the output of the decoder is active low.
