Filed:

Sep 30, 2011

Appl. No.:

13/249600

Inventors:

Jonathan H. Liu - San Diego CA, US

Assignee:

QUALCOMM INCORPORATED - San Diego CA

International Classification:

G06F 1/26

US Classification:

713300

Abstract:

Systems and methods for improving effective aging of a multi-core processor. Aging characteristics of the two or more cores of the multi-core processor are determined. Priority determination logic is configured to assign priorities for powering on the cores based on the aging characteristics. Optionally, an operating environment is detected and assigning priorities to the cores is based on a relative power consumption of each of the cores and the operating environment, in order to improve battery life.

Abstract:

A method of operation of a memory device includes, for each operating frequency of multiple operating frequencies, determining a target voltage level of a supply voltage. For example, a first target voltage level for a first operating frequency of the multiple operating frequencies is determined. The method includes accessing first data from the memory device while the memory device is operating at the first operating frequency and is powered by the supply voltage having a first voltage level. The method includes determining a first number of errors associated with the first data. The method further includes, in response to the first number of errors satisfying a threshold, adjusting the supply voltage to a second voltage level that is greater than the first voltage level.
