Abstract: Methods and systems for managing unlocking of an electronic device are provided. A method includes receiving an unlocking input from a user, authenticating the unlocking input, generating a first pre-wakeup command of initializing a progress action for the electronic device, generating a second pre-wakeup command of whether to complete the progress action or to retrogress the progress action based on the authenticating of the unlocking input, and determining whether to unlock the electronic device based on the second pre-wakeup command.

Abstract: A system and method for implementing asynchronous READ/WRITE operations in a Double Data Rate (DDR) controller to reduce Dynamic Random Access Memory (DRAM) access latency. The system provides a program configurable interface to the DDR controller for pre-fetching data from a memory address of interest into cache, for serving an asynchronous READ operation. The asynchronous READ operation minimizes or reduces pre-charge latency, Row Address Select (RAS) latency, and Column Address Select (CAS) latency. The system provides a program configurable interface to the DDR controller the read operation or the write operation being for providing buffer data directly to the DDR controller to handle an asynchronous WRITE operation.
