(d) 72.45
(e) 0.4475
(f) 52
(g) 4097.188

A-1 (a) 37

Q-1 A certain memory has capacity of 16K X 32. How many words does it store?

A-1 This memory consists of 16K words of 32 bits each. Therefore, the total number
of words contained in the memory is 16384 because 16 X 1024 = 16384. The bit
storage capacity of this memory is 16384 X 32 = 524288 bits.

Q-2 How many different addresses are required by the memory that contains 16K
words?

A-2 16384 addresses are required by the memory that contains 16K words.

DE unit-5 - 2 Mark question and answers

1. Explain ROM
A read only memory(ROM) is a device that includes both the decoder and the OR gates within a
single IC package. It consists of n input lines and m output lines. Each bit combination of the input
variables is called an address. Each bit combination that comes out of the output lines is called a
word. The number of distinct addresses possible with n input variables is 2n.

2. What are the types of ROM?
1.PROM 2.EPROM 3.EEPROM
3. Explain PROM.
PROM (Programmable Read Only Memory) It allows user to store data or program. PROMs use the
fuses with material like nichrome and polycrystalline. The user can blow these fuses by passing
around 20 to 50 mA of current for the period 5 to 20μs.The blowing of fuses is called programming
of ROM. The PROMs are one time programmable. Once programmed, the information is stored
permanent.
4. Explain EPROM.
EPROM(Erasable Programmable Read Only Memory) EPROM use MOS circuitry. They store 1’s and
0’s as a packet of charge in a buried layer of the IC chip. We can erase the stored data in the EPROMs
by exposing the chip to ultraviolet light via its quartz window for 15 to 20 minutes. It is not possible
to erase selective information. The chip can be reprogrammed.
5. Explain EEPROM.
EEPROM(Electrically Erasable Programmable Read Only Memory) EEPROM also use MOS circuitry.
Data is stored as charge or no charge on an insulated layer or an insulated floating gate in the
device. EEPROM allows selective erasing at the register level rather than erasing all the information
since the information can be changed by using electrical signals.
6. What is RAM?
Random Access Memory. Read and write operations can be carried out.
7. Define ROM
A read only memory is a device that includes both the decoder and the OR gates within a single IC
package.
8. Define address and word:
In a ROM, each bit combination of the input variable is called on address. Each bit combination that
comes out of the output lines is called a word.
9. What are the types of ROM.
1. Masked ROM. 2. Programmable Read only Memory 3. Erasable Programmable Read only memory.
4. Electrically Erasable Programmable Read only Memory.
10. What is programmable logic array? How it differs from ROM?
In some cases the number of don’t care conditions is excessive, it is more economical to use a
second type of LSI component called a PLA. A PLA is similar to a ROM in concept; however it does
not provide full decoding of the variables and does not generates all the minterms as in the ROM.
11.What is mask - programmable?
With a mask programmable PLA, the user must submit a PLA program table to the manufacturer.
12. What is field programmable logic array?
The second type of PLA is called a field programmable logic array. The user by means of certain
recommended procedures can program the EPLA.
13. List the major differences between PLA and PAL PLA:
Both AND and OR arrays are programmable and Complex Costlier than PAL PAL AND arrays are
programmable OR arrays are fixed Cheaper and Simpler
14. Define PLD.
Programmable Logic Devices consist of a large array of AND gates and OR gates that Can be
programmed to achieve specific logic functions.

DE UNIT-5 MEMEORY, PROGRAMMABLE LOGIC DEVICES AND LOGIC FAMILIES- Notes

UNIT-5
MEMEORY, PROGRAMMABLE LOGIC DEVICES AND LOGIC FAMILIES
 Memory is used for storing binary words.

 Reading is the process by which the data can be retrieved from memory:
 Writing is the process by which the data can be stored in the memory.
 Semiconductor memories make use of bipolar and MOS.
 Types of memories -
(a) RAM
(b) ROM
 RAM is the random access memory or read/write memory. One can read and write in RAM.
 ROM is the read only memory. One can only read from ROM nothing can be written in it.
 RAM is of two types:
(a) SRAM
(b) DRAM

 SRAM is also known as static RAM. In SRAM data will remain stored permanently as long
as power is supplied, they need not required rewriting periodically the data. The basic cell is
SRAM is a flip-flop.
 DRAM is also known as dynamic RAM. In DRAM rewriting periodically the data into
memory is required. The basic cell in DRAM is a capacitor.
 ROM is of four types:
(a) Masked ROM
(b) PROM
(c) EPROM V
(d) EEPROM V
 In masked ROM the data is stored permanently through photo masking during fabrication i.e.
programming is done through masking and metalization process.
 PROM is the programmable read only memory. it is programmed using PROM-programmer
and once the data is programmed (i.e. written) cannot be rewrite or changed again.
 EPROM is the erasable programmable read only memory. The user can erase and programme
this memory again and again. The EPROM is erased by exposing the chip from inside via
window at the top to ultra violet light.
 EEPROM is the electrically erasable. programmable read only memory. its function is similar
to EPROM but instead UV light the data can be erased using electrical signals.

PLDs (Programmable Logic Devices):

 There are of three types
(a) PAL
(b) PLA
(c) PGA or FPGA.

 PAL are the programmable arary logic in which AND gate arrays are programmable and OR
gate arrays are fixed.
 PLAs are programmable logic arrays in which AND-OR gate arrays are used and
programmed for specific logic functions.
 FPGA is the field programmable gate array. It consists of logic blocks i.e. an array of circuit
elements.
