Content-addressable memory is a special type of computer memory that stores data, likeRAM. In RAM, the central processing unit (CPU) can only access the data by specifying the memory address and reading out the data. CAM can also essentially work in reverse; the CPU specifies what data it ...
Ternary content-addressable memory (TCAM) is a type of content-addressable memory (CAM) that allows a third state of “don’t care” or “X” in one or more of the bits of stored data, adding flexibility to the search. The word “ternary” refers to the number of inputs that the me...
Megabyte is a multiplier of byte, which is the smallest unit ofaddressablememory in most computer architectures. A byte is typically made up of eight binary digits (bits). The eight-bit byte is considered today's de facto standard for byte length, although that number can vary depending on ...
What is dynamic memory allocation? Suppose that a 16M X 16 main memory is built using 512K X 8 RAM chips and memory is word addressable. a) How many RAM chips are necessary? b) How many RAM chips are needed for each memory word? c) Ho ...
What is cloud storage? (a) Define primary memory. (b) In a computer system, how they affect performance in general? What is a data instance? Suppose that a 4M X 32 main memory is built using 1M X 8 RAM chips and that memory is word addressable. a) How many RAM chips are necessary...
To retrieve a word from associative memory, a search key (or descriptor) must be presented that represents particular values of all or some of the bits of the word. This key is compared in parallel with the corresponding lock or tag bits of all stored words, and all words matching this ...
SRAM memory cell operationThe operation of the SRAM memory cell is relatively straightforward. When the cell is selected, the value to be written is stored in the cross-coupled flip-flops.The cells are arranged in a matrix, with each cell individually addressable....
Limitation of Flash Memory Although Flash memory gives many advantages, yet it has some flaw. 1) We can quickly read or programmed a byte at a time, but we cannot erase a byte or word. It can delete data in blocks at a time. 2) Bit flipping: Bit Flipping problem is more occur in...
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. Word ...
as well as the instructions that direct that manipulation The program must be organized such that the CPU does not read a non-instruction word when it expects to see an instruction.The CPU can rapidly access any data stored in memory; but often the memory is not large enough to store the...
