SoftRAM and SoftRAM95 were system software products that claimed to increase or even double the available random-access memory in Microsoft Windows without the need for a hardware upgrade, which is theoretically possible using memory compression. However, it later emerged that the program did not have any actual compression algorithm. [1]
Software using unmanaged memory can cause stability problems. Specifically in IBMPC based 32-bit operating systems, some RAM drives are able to use any 'unmanaged' or 'invisible' RAM below 4 GB in the memory map (known as the 3 GB barrier) i.e. RAM in the 'PCI hole'.
DiskStation Manager (DSM) is a Linux-based operating system by Synology. Synology's software architecture allows for third-party add-on application integration. Hundreds of third-party applications are available in addition to Synology's own catalog. Command line access via SSH or Telnet is available.
IWA supports Dynamic In-memory (in-memory columnar processing) Parallel Vector Processing, Actionable Compression, and Data Skipping technologies, collectively called "Blink Technology" by IBM (the same technology underlying IBM BLU Acceleration). The Informix Advanced Enterprise and Advanced Workgroup Editions include IWA. Released: March 2011.
Upgrades of software introduce the risk that the new version (or patch) will contain a bug, causing the program to malfunction in some way or not to function at all. For example, in October 2005, a glitch in a software upgrade caused trading on the Tokyo Stock Exchange to shut down for most of the day. [3]
Effective memory bandwidth utilization varies from 33% to 50% for smallest packets of 32 bytes; and from 45% to 85% for 128 byte packets. [ 7 ] As reported at the HotChips 23 conference in 2011, the first generation of HMC demonstration cubes with four 50 nm DRAM memory dies and one 90 nm logic die with total capacity of 512 MB and size 27×27 ...
Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.
The memory is divided into several equally sized but independent sections called banks, allowing the device to operate on a memory access command in each bank simultaneously and speed up access in an interleaved fashion. This allows SDRAMs to achieve greater concurrency and higher data transfer rates than asynchronous DRAMs could.
