FACTS ON MEMORY SPEED
Sunday, November 29th, 2009 | Author: admin

Speed of memory is measured in megahertz or gigahertz or in terms of access time. Access time measures from when the memory module receives a data request to when the data becomes available. Memory chips and modules are marked with access time in the range of 80 ns to 50 ns. Lower the access time greater is the speed. Speed in here just indicates how quickly the memory module can deliver data on request once that request is made. The memory chips have the ability to synchronize with computer’s system clock making it easier to calculate the speeds. Whether the speed is in gigahertz or megahertz it becomes easier to compare speeds of different components and synchronize their functions. In order to understand speed of the system better it is essential to understand concept of system clock which resides on the motherboard. It sends signals to all other components in rhythm. It is possible for the components of the system to run slower than the system clock. Components of different speeds require a multiplication or division factor to synchronize the components. This is taken care of by system clock.
