Abstract

Today, flash memory (a type of semiconductor device) is becoming a popular data storage device in most electronic mobile devices. The reasons that make it become popular include small size and light weight nature, less noise, solid-state reliability, low power consumption, and better shock resistant. However, its two hardware characteristics, called out-place updating and garbage collection indirectly affect the performance of it superiority features. To overcome these limitations, this paper proposes a page allocation algorithm that based on page appearance regularity. The performance of the allocation scheme is confirmed by trace-driven simulations and the merit of the proposed algorithm is justified in terms of the number of active block requirement.
