Cache memory is composed of 2 types of memory:
Cache memory also contains controller logic to coordinate the necessary actions.
The first computer built to have what we now call Cache memory was the IBM Stretch 7030 introduced in 1961. However IBM at the time called this feature "Virtual memory". (Confusing isn't it?)
High-speed and costlier SRAM chips are used for memory-caching, whereas the conventional main memory [DRAM] is used for disk-caching.
TCAM = Tagged Content Addressable Memory
A specialized type of RAM.

sram is used for cache for cache memory.
Static RAM or SRAM
Cache is a high speed buffer memory for storing automatically small areas of frequently used memory, so that the machine does not have to wait for the full memory access time every time it needs to access the data in those areas.Most computers have separate but similar cache memories for data and instructions. This allows the same access time advantages for both, but as data and instructions are usually in different places in memory eliminates any conflicts in usage.Some computers have multiple levels of different speed cache with different sizes. These are typically referred to as L1 cache, L2 cache, L3 cache, etc. with L1 being the fastest, most expensive, smallest size cache closest to the processor; the others are successively closer to the main memory.

Some examples of Random Access Memory (RAM) include: DDR4: A type of RAM commonly used in desktop computers and high-performance laptops. SDRAM: Synchronous Dynamic RAM, a type of RAM used in older computer systems. LPDDR4: Low-Power DDR4, a type of RAM commonly used in mobile devices like smartphones and tablets. SRAM: Static RAM, faster and more expensive than dynamic RAM, often used in cache memory and embedded systems. DDR3: Another type of RAM commonly used in older desktop computers and laptops.
sram is used for cache for cache memory.
Cache is a special kind of memory which is can be used as a spare to store data
Static RAM or SRAM
Cache memory was invented by Maurice Wilkes. It was intended to be used as a type of recent data safeguard between the physical memory and the processor.
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
cache is the type of memory within the CPU. It is extremely fast and is very small storage wise (it only comes in megabytes)
Cache Memory is needed because Hardware implements cache as a block of memory for temporary storage likely to be used again.
Usually high speed SRAM with CAM (content addressable memory) line address tags.
The data that are frequently used goes in the cache memory...
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.
Virtual memory is a type of memory that is allocated by the operating system and is used to speed up operations. Cache memory is RAM that the CPU can access faster than regular ram which is considered physical memory. When the CPU is looking for data, it checks the cache memory first, recently used data will still be in the cache. If it does not find it there, it moves on to use the physical memory. Anytime a program or file is opened, it is first loaded into RAM (physical memory).
