ABSTRACT:
A method for detecting the data strobe signal from a Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM). The method executes a data reading process at first and records the latency period of the data read process to be a basis for detecting the arrival timing of the preamble in the data strobe signals in the subsequent data reading process.
