Abstract
The subject system and method are generally directed to ensuring reliable high speed data transfer in multiple data rate nonvolatile memory, such as double data rate (DDR) nonvolatile NAND flash memory and the like. The system and method provide measures to achieve read and write training for data signals (DQ) and the data strobe signal (DQS), one relative to the other. In such manner, high speed data transfers to and from nonvolatile memory such as flash devices may be performed with a reduced risk of data loss even at high operational frequencies.
