  • FlexRAM: Toward an Advanced Intelligent Memory System A Retrospective Paper lead to our ICCD-1999 FlexRAM paper started in 1996. At that time, there was great interest in potential of integrating compute capabilities in large DRAM memories — an architecture called processing in memory (PIM) or intelligent memory.

  • The developers chose the 8088 over the 8086 because, while the 8088 worked on a 16-bit basis internally, it only communicated with the outside world using an 8-bit data bus. Since the 8-bit DataMaster data bus already existed, the 8088 was the obvious choice. This bus connects the motherboard of the PC, where the processor and its support chips are resident, to the memory and the expansion boards, which are plugged into the expansion slots.

  • Operating Systems interpret user commands and instructions (like typing on the keyboard or clicking with the mouse) and send requests to the proper application or device. An OS not only provides a user interface (text or graphic) to access/organize/manipulate/store data, but can also provide security and multitasking capabilities. Generally the OS is made up of a few core files with additional files for extended functionality and backward capability.

  • Speed Memory will enable you to remember lists of objects not only in order, but also in reverse and random order; to remember names and faces, as well as facts associated with them; to remember speeches, scripts, articles, jokes and narratives; to remember dates, prices, numbers (including telephone numbers!) and anniversaries; and to remember far more readily languages and information relevant to examinations. You will also be able to perform 'memory feats' with * number games and cards....

  • What happens when we turn on our workstation and try to boot into Linux? The BIOS checks the system. The Boot loader finds the kernel image, loads it into memory, and starts it. The kernel initializes devices and their drivers. The kernel mounts the root filesystem. The kernel starts the init program. init gets the rest of the processes started The last process that init starts will allow you to login.

  • We wish to construct a system which possesses so-called associative memory. This is definable generally as a process by which an input, considered as a “key”, to a memory system is able to evoke, in a highly selective fashion, a specific response associated with that key, at the system output. The signalresponse association should be “robust”, that is, a “noisy” or “incomplete” input signal should none the less invoke the correct response—or at least an acceptable response. Such a system is also called a content addressable memory....
