Abstract
A mobile device including a system-on-chip, which includes a mobile device control module to execute application programs for the mobile device, a solid-state disk (SSD) control module to control SSD operations, a random access memory (RAM) control module to store both SSD-related data and mobile device-related data in a single RAM, and a nonvolatile (NV) memory control module to control reading from and writing to the NV memory array. Data in the single RAM is stored into the NV memory array during an idle mode. The single RAM is powered down during the idle mode after the data in the single RAM has been stored into the NV memory array. The stored data in the NV memory array is loaded into the single RAM during a re-start mode.
Claims12
A mobile device, comprising:
- a system-on-chip (SOC) including
- a mobile device control module configured to execute application programs for the mobile device;
- a solid-state disk (SSD) control module configured to control SSD operations;
- and
- a random access memory (RAM) control module configured to communicate with the mobile device control module and the SSD control module and to store both SSD-related data and mobile device-related data in a single RAM;
- and
- a nonvolatile (NV) memory control module configured to communicate with the SSD control module and a NV memory array, and to control reading from and writing to the NV memory array,
- wherein data in the single RAM is stored into the NV memory array during an idle mode,
- wherein the single RAM is powered down during the idle mode after the data in the single RAM has been stored into the NV memory array, and
- wherein the stored data in the NV memory array is loaded into the single RAM during a re-start mode.
