    Publication number: 20220405016
    Abstract: Technologies for converting serial data stream to a parallel data and strobe scheme with data strobe preamble information in the serial data stream are described. A device includes an interface circuit that receives a serial data stream and converts the serial data stream to parallel data and a data strobe (DQS) signal associated with the parallel data using N-bit header fields inserted into the serial data stream. The N-bit header fields specify DQS preamble information for the parallel data.

  • SEMI RECEIVER SIDE WRITE TRAINING FOR NON-VOLATILE MEMORY SYSTEM
    Publication number: 20220405190
    Abstract: Technology is disclosed herein for semi receiver side write training in a non-volatile memory system. The transmitting device has delay taps that control the delay between a data strobe signal and data signals sent on the communication bus. The delay taps on the transmitting device are more precise that can typically be fabricated on the receiving device (e.g., NAND memory die). However, the receiving device performs the comparisons between test data and expected data, which alleviates the need to read back the test data. After the different delays have been tested, the receiving device informs the transmitting device of the shortest and longest delays for which data was validly received. The transmitting device then sets the delay taps based on this information. Moreover, the write training can be performed in parallel on many receiving devices, which is very efficient.
