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 bits are required for the address?
Therefore 32 bits are required to uniquely address each 32-bit word. Therefore 34 bits are required to uniquely address each byte.
How many bits are required for to address a 4M x 32 memory if the main memory is byte addressable or the memory is word addressable?
4M X 8 bit memory requires 21 bit addresses if it is word-addressable and word size is 16 bits. 4M X 8 bit memory requires 20 bit addresses if it is word-addressable and word size is 32 bits.
How many bits are in a 8m x 16 memory?
“8Mx16” means 8 million words (23-bit address bus) and 16 bits per word (16-bit data bus). The total capacity is 128 million data bits. Some memory devices can be reconfigured by connecting a mode pin high or low. For example, that 8Mx16 memory might be reconfigurable as a 16Mx8 memory.
How many bits are in 1m?
1 Megabyte = 8 × 106 Bits. 1 Megabyte = 8 × 1000000 Bits. 1 MB = 8000000 b. There are 8000000 Bits in a Megabyte.
How many addresses can be represented by 4 bits?
In hexadecimal notation, 4 bits (a nibble) are represented by a single digit. There is obviously a problem with this since 4 bits gives 16 possible combinations, and there are only 10 unique decimal digits, 0 to 9.
How many bits are required to address 128mb of memory?
How many bits are needed to address any single word in memory? The memory address space is 128 MB, which means 227. However, each word is 8 (23) bytes, which means that you have 224 words. This means you need log2 224 or 24 bits, to address each word.
What is 4M in memory?
Memory is often referred to using the notation length X width (L X W). For example, 4M X 8 means the memory is 4M long (it has 4M = 2^2 X 2^20 = 2^22 items) and each item is 8 bits wide (which means that each item is a byte).
How do you calculate byte addressable memory?
To calculate the number of address bits I use : log2(n) where n is the number of bits of the memory. I.e for 1gb (1024mb * 1024 * 1024)= 1073741824 bits so therefore log2(1073741824 ) = 30 meaning a 1gb memory would require 30 address bits.
How many 256×8 RAM chips are needed to provide a memory capacity of 4096 bytes?
The required capacity is 4096 bytes, hence . Hence the number of such RAM chips required, or 16 chips.
How many address bits are there in memory 4096 <UNK> 16?
So, if N = 4096, you’ll need 12 address bits.
What is word addressable memory?
A memory word is certain bytes that bidirectional data bus can carry at a time. Say, size of the data bus is 16 bits, it means it can carry a maximum of 16 bits of data at a time. And such memory are called word addressable memory. In a 32 bit machine, size of the data bus is 32 bits or 4 bytes.
What is 8M memory?
The 8M Memory Pack is the standard memory cartridge for all Satellaview-compatible games, including BS-X, Derby Stallion 96, Same Game and so forth. For the BS-X cartridge, Memory packs stored data that the BS-X could boot up, which ranged from Downloadable Magazines and Booklets to Downloadable Games.
What is the amount of bits that require to address 256MB?
For example, you can store 256 different values in an 8 bit number, so 8 bits can address 256 bytes.
Is 1gb 1000mb or 1024mb?
A megabyte is a unit of information or computer storage equal to 1,048,576 bytes. A Gigabyte is approximately 1000 Megabytes. A gigabyte is a unit of information or computer storage meaning approximately 1.07 billion bytes. But 1 gigabyte = 1024 megabytes and this still be correct using the other acceptable standards.
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) Personal Computer 256MB Fileserver 4GB Database Mainframe 32GB.
What are the 16 4-bit numbers?
Hexadecimal Numbers Decimal Number 4-bit Binary Number Hexadecimal Number 15 1111 F 16 0001 0000 10 (1+0) 17 0001 0001 11 (1+1) Continuing upwards in groups of four.
How many numbers can be represented with 16 bits?
16 bit unsigned numbers A halfword or double byte contains 16 bits. A word contains 32 bits. There are 65,536 different unsigned 16-bit numbers. The smallest unsigned 16-bit number is 0 and the largest is 65535.
Are 4 bits enough to store 8 directions?
Four bits are not enough to store the eight directions. Eight bits are needed for the new version of the game.
How many address bits are required for a 1024 * 8 memory?
Or 1024*8 gives 8192, or 2^13. so 13 bits. If it ain’t a 1024 bits multiplied by 8 bits, or there are 1024 arrays of each size of 8 bit, then 1024 arrays, so 10 bits of addresses will do it.
How many address bits are required to represent 32k memory?
2e10 = 1024, so you need 10 bits to address every byte in a kilobyte. Likewise, you need 20 bits to address every byte in a megabyte, and 30 bits to address every byte in a gigabyte. 2e32 = 4294967296, which is the number of bytes in 4 gigabytes, so you need a 32 bit address for 4 GB of memory.
How many bits are required in the address for memory of 32gb?
432 bytes = 32 Mb. So you will need, at least 25 bits to address a single byte in that memory scheme.
What is the difference in capacity between a 4M memory chip and 4M of computer memory?
What is the difference in capacity between a 4M memory chip and 4M of computer memory? The more address pins, the more memory locations are inside the chip.
What is M in data size?
The smallest unit of measurement used for measuring data is a bit. Since most files contain thousands of bytes, file sizes are often measured in kilobytes. Larger files, such as images, videos, and audio files, contain millions of bytes and therefore are measured in megabytes.
How many bits would you need to read the contents of a memory containing 2000 words?
With regard to memory, 2k usually means 2*(2^10) — that is, 2048. Now, depending on context, that may be 2048 bits, 2048 bytes ( 8*2048 bits), or 2048 words — (word-size-in-bits) * 2048 bits.
What is bit addressable and byte addressable?
They are not really using the terms right, byte addressable is what we are used to an address represents a unique byte in memory or the memory space. Bit addressable would mean that each bit in the memory space has a unique address, which is not the case.
