Publication number: 20190294548Abstract: Aspects of a prefetch module for high throughput memory transfers is described. Data stored in a row buffer of a memory device can be quickly transferred over a serial link to a prefetch buffer. In one example, a number of respective serial links can be used to transfer the data stored in several row buffers of respective memory devices to the prefetch buffer. In the prefetch buffer, all the data from the memory devices is stored in a data cache. Once the data is cached at the prefetch buffer, a memory controller can access it more quickly in any suitable way. As compared to conventional approaches, the embodiments can be relied upon to avoid a significant amount of latency in memory read and write operations with memory modules.Type: ApplicationFiled: March 21, 2018Publication date: September 26, 2019Inventors: Waseem Kraipak, Thomas Edward Sellinger, Christopher Leo Collins

Patent number: 6542507Abstract: The present invention, generally speaking, uses input buffering and output control to provide a high-speed, high-performance digital traffic switch. This approach solves all of the problems noted above with respect to the prior art (input buffering/input control, output buffering/output control). Dropped discrete information units (cells) are dropped at the input port, and so will not be transmitted across the switch fabric. This reduces the traffic load on the switch fabric during congested periods, and makes the switch fabric easier to design and expand. Input buffering/output control allows for the use of smaller buffers than output buffered/output control architectures for the same level of “discrete information unit (cell) drop” performance, and scales well to larger systems. Input buffering/output control provides all the information necessary to the output (data flow) controller necessary to implement very precise control algorithms.Type: GrantFiled: April 16, 1998Date of Patent: April 1, 2003Assignee: AlcatelInventors: Todd L.
