Prefetch module for high throughput memory transfers

A method to prefetch data, comprising:

• receiving, from a memory controller, a request for data associated with an address;
• determining whether a data cache contains the data associated with the address based on a comparison of the address with a tag address stored in a tag memory and a validity bit for the tag address stored in the tag memory;
• based on a determination that the data cache does not contain the data associated with the address, opening a row of memory in at least one of a plurality of memory devices on a memory module based on the address, the row of memory being associated with a plurality of columns of memory;
• receiving, by a serdes, data from the plurality of columns of memory;
• caching the data from the plurality of columns of memory in a data cache;
• and
• returning the data from the data cache to the memory controller.

A prefetch module, comprising:

• a serdes configured to serialize data for transmission to a memory device and to deserialize data received from a row buffer of the memory devices;
• a data cache configured to store data received over the serdes;
• and
• a prefetch control module configured to coordinate data exchange between a memory controller and the memory device over the serdes based on interface signals defined by an interface protocol of the memory controller.
