Consider a TLB with 3 entries that uses an LRU (least recently used) algorithm. Assume the following sequence of virtual page number accesses: Virtual page 9, then Virtual page 7, then Virtual page 9, then Virtual page 5, then Virtual page 3, then Virtual page 7, then Virtual page 5, then Virtual page 3, then Virtual page 3, then Virtual page 2 What was the TLB hit rate (as a percentage)? the 2 ends up in slot (0-2)??

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:
