Question
Exercise 1 TFThe more address pins, the more memory locations are inside the chip. T FThe more data pins, the more each location inside the chip will hold. Themore datapins,the higher thecapacityofthememorychip. To access DRAM, the RAS address is provided first and then the CAS address While F contains both code and data, ports contain only code T F In instruction "IN AL 78H", register AL is the source. Exercise2 What is the difference between a 4M memory chip and 4M of computer memory as far as capacity is concerned? Exercise 3 Find the capacity, address, and data pins for the following memory organizations. a) 8Gx 8 ROM b) 16K x 8 SRAM c) 1M x 1 DRAM Exercise 4 Using NAND gates and inverters, design decoding circuitry for the address range 9C1000H- 9CIFFFH.Explanation / Answer
Answer 1:
a. TRUE , More address pins means more addresses, means more memory locations.
b, FALSE , Data pins are the same as address pins, only the interpretation is different. Also, the data to be stored in a location doesnt depent on data pins, but on the design of the chip. Generally, it's 1 byte per location.
c. TRUE , data pins are same as address pins, so, more addresses means generally a larger capacity, since we can address more locations.
d. TRUE , In DRAM operation, RAS signal is given first to select the appropriate row, and then CAS, to select the desired column.
e. FALSE, first operand in x86 intel assembly is always the destination. Not source
