How many RAM chips are necessary?

For a word-addressable main memory which is built using RAM chips. Hence, 16 RAM chips of size are required to construct a main memory. Further they can be arranged in 8 rows of 2 columns each.

How many address and data lines will be there for a 16M x 16 memory system?

d. None of the above Correct solution is (c). Since there are 16M words, the number of address lines will be 24, since 224 = 16M. Also since the word size is 32 bits, the number of data lines will also be 32.

How many address and data lines will be there for a 32m x 8 memory system?

(a) 32 x 8 32 = 25, so 32 x 8 takes 5 address lines and 8 data lines, for a total of 5 + 8 = 13 I/O lines. (b) 4M x 16 4M = 4 × 220 = 222, so 4M x 16 takes 22 address lines and 16 data lines, for a total of 22 + 16 = 38 I/O lines.

How many bits of address are required for this entire multi chip memory?

In the third we use 8 RAM chips, each chip gives us 1 bit – to read an 8 bit memory word, we would have to access all 8 RAM chips simultaneously and concatenate the bits. Main memories are normally bigger than the size of a single RAM chip….Main Memory (RAM)

How many bits are required to address a 4M 16 main memory if the memory is word addressable?

4M * 16 = 2^2 * 2^20 * (2^4 / 2^3) (16 bits / 8 bits is a byte) = 2^2 * 2^20 * 2^1 = 2^23 => 23 bits.

How many address bits is needed for a 64m bit chip?

Each RAM chip has 64 x 1 byte = 64 bytes. Thus the number of chips to address a memory capacity of 2048 bytes will be, 2048/64 = 32 chips…. GO Book for GATECSE 2022….How many 128×8 RAM chips are needed to provide?

Why is RAM faster than rom?

RAM is faster than ROM just because writing data to a ROM chip is a slow process, whereas writing data to a RAM chip is a faster process. A RAM chip can store multiple gigabytes (GB) of data, up to 16 GB or more per chip; A ROM chip typically stores only several megabytes (MB) of data, up to 4 MB or more per chip.

Why is cache memory faster than RAM?

Cache memory allows for faster access to data for two reasons: cache memory stores instructions the processor may require next, which can then be retrieved faster than if they were held in RAM.

Why is RAM faster than ROM?

How many address lines are required for accessing the memory chip of 16k RAM?

There are 1024 bytes in one k byte. A 16k ram would therefore need 1024*16 = 16384 addresses.

What is a 16 bit RAM?

16 bit = 65,536 bytes (64 Kilobytes) 32 bit = 4,294,967,296 bytes (4 Gigabytes) 64 bit = 18,446,744,073,709,551,616 (16 Exabytes)

How many 256 8 RAM chips are needed to provide a memory capacity of 4096 bytes?

L=2 8 ; W=8. The required capacity is 4096 bytes, hence . Hence the number of such RAM chips required, or 16 chips.
