Disclosed is an improved approach to implement training for memory technologies, where a data valid window is re-determined using boundary information for a new data valid window. The information obtained for the new location of the first edge is used to minimize the computational resources required to identify the location of the second edge. This greatly improves the efficiency of the process to perform the re-training.

Method and system for efficient re-determination of a data valid window

A system and method are provided for ensuring reliable data transfers by automatically recovering from un-correctable errors detected in data traversing throughout a system and being retrieved from an unreliable intermediate data buffer between a first memory and a secondary slower memory. Additionally, measures to compensate for the use of unreliable or error-prone components and interconnects, such as, for example, SRAM memory as a temporary buffer are provided. Further, measures to detect and correct errors&#x2014;whatever the type&#x2014;injected or occurring at any stage throughout traversal of the system are provided.
