Latest Patents

One of Guangxi Ying's latest patents is titled "Methods and systems for implementing high bandwidth memory command address bus training." This invention provides a method to initiate Command Address (CA) training on High Memory Bandwidth, optimizing CA bus setup and hold times relative to the memory clock. The HBM protocol does not define any way to support CA training, yet it operates at a very high frequency. This high frequency complicates the timing on the CA Bus-Row/Column command bus and CKE. Therefore, executing CA training before any normal operation is essential to ensure optimal setup and hold timings. The CA training leverages protocol-based instructions to initialize and implement the training process.

Another significant patent by Guangxi Ying is "Method and apparatus for high bandwidth memory read and write data path training." This invention relates to methods and apparatuses for performing read and write data path training in HBMs. The embodiments configure HBM mode registers for read and write data path training using an IEEE 1500 interface, which simplifies the process compared to traditional scenarios. Additionally, the logic for performing read and write data path training operates independently from normal memory access functionality in the host, allowing it to interact with a PHY core for training purposes.
