Question

y are the input variables to a PAL buffered? Select one O A. To prevent power drain when the inputs are not changing B. To protect the inputs during programming of the PAL O C. To allow the input to be enabled D. To prevent loading by a large number of AND gate inputs The main difference between a PAL and a GAL is Select one: O A. a GAL can implement more complicated expressions than a PAL because it has more product terms B. a PAL is designed for SOP equations while a GAL is designed for POS O C. a GAL has a programmable AND and OR matrix O D. a GAL uses EECMOS technology and is re-programmable Which of the following is not a type of memory? Select one: O A. EEPROM O B. RAM O C. FPROM O D. ROM

Answer 1

1. Answer is 'D'

Buffers are used for reducing load on input lines from large number of AND gates

2. 'D'

GAL is erasable and re-programmble

3. Of the given options RAM is more suitable to be the answer, all other variations of ROM which is more a memory unit

So the answer is 'B'
