Abstract
System and methods for booting a system-on-chip (SOC) in an enhanced memory mode are described herein. In one aspect, an enhanced memory mode indicator may be read to create a trusted channel to a non-volatile random-access memory (NVRAM). The NVRAM may be logically connected to the SOC. In an aspect, the NVRAM may be secured prior to the creation of the trusted channel. Once the secure channel to NVRAM has been created, the SOC may operate in an enhanced memory mode. Prior to the SOC powering down, the system may store an indicator operable to enable a subsequent boot of the SOC in the power saving mode. The SOC may be operable to switch between the power saving mode and a normal mode depending on the operational requirements of the portable computing device in which the SOC is implemented.
