( Computing)


  • It Is Small faster Memory which stores copies of the data from the most frequently used by main memory location
  • Actually it is placed between Microprocessor & RAM.
  • it stored address of memory location by which microprocessor don't need to cache its address again and again. Once Cache Memory Cached That Address then RAM and Microprocessor Directly Operate it rapidly.
uses:
  • Due to cache memory,average latency memory is increases
  • and also It gives faster access to currently needed data
  • it also reduces average time of accessing memory for RAM and Microprocessor
  • It is special type of memory which is use to fast access to microprocessor
