Abstract

A mobile device includes a system-on-chip (SOC) that includes a mobile device control module, a solid state disk (SSD) control module, and a random access memory (RAM) control module. The mobile device control module executes application programs for the mobile device. The solid-state disk (SSD) control module controls SSD operations. The RAM control module communicates with the mobile device control module and the SSD control module and stores both SSD-related data and mobile device-related data in a single RAM.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Invention Patent Application No. 12 / 501,728, filed July 13, 2009, and US Provisional Application No. 61 / 080,510, filed July 14, 2008.
