US Patent 10,268,608 Summary

• Title: Memory module with timing-controlled data paths in distributed data buffers
• Assignee: Netlist Inc
• Inventors: Hyun Lee, Jayesh R. Bhakta
• Filing Date: November 21, 2017
• Issue Date: April 23, 2019
• Abstract: A memory module operable in a memory system with a memory controller comprises memory devices, a module control circuit, and a plurality of buffer circuits coupled between respective sets of data/strobe signal lines in a data bus and respective sets of the memory devices. Each buffer circuit includes a data path for each data signal line in the corresponding set of data/strobe signal lines, and a command processing circuit configured to decode module control signals from the module control circuit and to control the data path according to these signals. The data path for each data signal line includes at least one tristate buffer controlled by the command processing circuit and a delay circuit configured to delay a signal through the data path by an amount determined by the command processing circuit in response to at least one of the module control signals.
