Abstract: The present disclosure relates to field of Dual In-Line Memory Modules that discloses method and system for generating memory maps. The method comprises detecting, by computing system, at least one of DIMM and one or more Dynamic Random Access Memory (DRAM) chips associated with computing system. The one or more accelerators are configured in at least one of DIMM and one or more DRAM chips. Further, the method includes determining accelerator information for each of one or more accelerators via at least one of Serial Presence Detect (SPD) and Multi-Purpose Register (MPR) associated with at least one of DIMM and one or more DRAM chips. Method includes generating unique memory map for each of one or more accelerators based on accelerator information of corresponding one or more accelerators. As a result, performance of computing system may be improved as accelerator capabilities of one or more accelerators are effectively utilized.

Abstract: A method for securing one or more cells of a dynamic random-access memory (DRAM) device embedded in a system includes: (1) triggering, by one of a boot loader, an operating system (OS) and an application, a system management interrupt (SMI), (2) invoking, by a basic input/output system (BIOS), a BIOS SMI handler, (3) converting a physical address of secure data to a DRAM address using a reliability, availability and serviceability (RAS) protocol of a BIOS, and (4) performing a write protect operation on the secure data present in the DRAM device by issuing a device-supported security command in a BIOS SMI service routine.

Abstract: A Near Memory Processing (NMP) dual in-line memory module (DIMM) for managing an address map is provided. The NMP DIMM includes: a static random-access memory (SRAM) provided on a Double Data Rate (DDR) interface; and an address management controller coupled to the SRAM, and configured to control the NMP DIMM to: receive a first indication from a host system to perform interface training for operating an SRAM space; perform the interface training using a first address map based on the first indication; receive a second indication from the host system indicating completion of the interface training for operating the SRAM space; switch from the first address map to a second address map for operating the SRAM space in response based on the second indication; and operate the SRAM space using the second address map.
