Write-through cache

Updated: 04/26/2017 by Computer Hope

A write-through cache is a component of memory that allows future data requests to be accessed faster. It accomplishes this task by writing to both the cache and main memory at the same time. The data written to cache is used to speed up requests. The data in main memory acts as a backup, ensuring cached data is not lost if there is an unexpected data loss condition (crash).
