Patent number: 12561251Abstract: Disclosed is a dynamic random access memory (DRAM) that includes a plurality of data rows and a plurality of tag rows. The DRAM includes a communication interface to receive a first group of address bits. The DRAM includes one or more comparators to generate a tag match indication and one or more set bits based on the first group of address bits and a first group of tag information bits from the plurality of tag rows. The one or more comparators are further to combine, based on the tag match indication, the one or more set bits and the first group of address bits to generate a second group of address bits.Type: GrantFiled: July 24, 2024Date of Patent: February 24, 2026Assignee: Rambus Inc.Inventors: Thomas Vogelsang, Frederick A. Ware, Michael Raymond Miller, Collins Williams

Patent number: 12367921Abstract: Disclosed is a memory system including a memory component having at least one tag row and at least one data row and multiple ways to hold a data group as a cache-line or cache-block. The memory system includes a memory controller that is connectable to the memory component to implement a cache and operable with the memory controller and the memory component in each of a plurality of operating modes including a first and second operating mode having differing addressing and timing requirements for accessing the data group. The first operating mode having placement of each of at least two ways of a data group in differing rows in the memory component, with tag access and data access not overlapped. The second operating mode having placement of all ways of a data group in a same row in the memory component, with tag access and data access overlapped.Type: GrantFiled: November 6, 2023Date of Patent: July 22, 2025Assignee: Rambus Inc.Inventors: Frederick A. Ware, Thomas Vogelsang, Michael Raymond Miller, Collins Williams

Publication number: 20250021484Abstract: Disclosed is a dynamic random access memory that has columns, data rows, tag rows and comparators. Each comparator compares address bits and tag information bits from the tag rows to determine a cache hit and generate address bits to access data information in the DRAM as a multiway set associative cache.Type: ApplicationFiled: July 24, 2024Publication date: January 16, 2025Inventors: Thomas Vogelsang, Frederick A. Ware, Michael Raymond Miller, Collins Williams

Patent number: 12147345Abstract: Memory controllers, devices, modules, systems and associated methods are disclosed. In one embodiment, a memory system is disclosed. The memory system includes volatile memory configured as a cache. The cache stores first data at first storage locations. Backing storage media couples to the cache. The backing storage media stores second data in second storage locations corresponding to the first data. Logic uses a presence or status of first data in the first storage locations to cease maintenance operations to the stored second data in the second storage locations.Type: GrantFiled: December 2, 2022Date of Patent: November 19, 2024Assignee: Rambus Inc.Inventors: Collins Williams, Michael Miller, Kenneth Wright

Publication number: 20230418758Abstract: A device includes a cache memory and a memory controller coupled to the cache memory. The memory controller is configured to receive a first read request from a cache controller over an interconnect, the first read request comprising first tag data identifying a first cache line in the cache memory, and determine that the first read request comprises a tag read request. The memory controller is further configured to read second tag data corresponding to the tag read request from the cache memory, compare the second tag data read from the cache memory to the first tag data received from the cache controller with the first read request, and if the second tag data matches the first tag data, initiate an action with respect to the first cache line in the cache memory.Type: ApplicationFiled: June 26, 2023Publication date: December 28, 2023Inventors: Michael Miller, Dennis Doidge, Collins Williams

Patent number: 11842762Abstract: Disclosed is a memory system that has a memory controller and may have a memory component. The memory component may be a dynamic random access memory (DRAM). The memory controller is connectable to the memory component. The memory component has at least one data row and at least one tag row different from and associated with the at least one data row. The memory system is to implement a cache having multiple ways to hold a data group. The memory controller is operable in each of a plurality of operating modes. The operating modes include a first operating mode and a second operating mode. The first operating mode and the second operating mode have differing addressing and timing for accessing the data group. The memory controller has cache read logic that sends a cache read command, cache results logic that receives a response from the memory component, and cache fetch logic.Type: GrantFiled: March 16, 2020Date of Patent: December 12, 2023Assignee: Rambus Inc.Inventors: Frederick Ware, Thomas Vogelsang, Michael Raymond Miller, Collins Williams
