Associative Memory Computer Organization and Architecture by admin - January 6, 2023January 7, 20230 Associative Memory Unlike the main memory which is accessed using the contents address and in sequential method, the associative memory is accessed by contents and is also called as the content addressable memory. For writing a word in memory, unused space is found by memory and the word written their. Word is read from memory by matching the word or its part with the contents/word stored in memory. Difference between main memory and associative or content addressable memory Main Memory Associative or Content addressable memory Memory accessed by using address of contents/words Memory is accessed by matching contents with word stored in memory To store a word, we assign the address and write the word at that address To write a word, memory finds the empty space and
Memory Organization Computer Organization and Architecture by admin - January 4, 20230 Memory Organization Every computer system has following types of memory devices. The different types of memory can be explained as the memory hierarchy. Memory Hierarchy: The total capacity of the memory in a system can be visualized as a hierarchy of memory devices. It includes all memory devices employed in a computer from large size but very slow-speed to small size but very-high speed devices. The memory hierarchy can be represented as shown in figure below. IOP is used to communication between main memory and the auxiliary memory. Cache is used to communicate between CPU and the main memory. Internal or the primary memory: The internal memory consists of random access memory (RAM), read only memory (ROM) and some high-speed memory such as cache memory.
