      NVRAM (Non-Volatile Random Access Memory)

      NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from

    • Unbuffered Memory

      Unbuffered Memory

      Unbuffered memory, or unregistered memory, is memory in which no hardware register exists between a RAM chip and a memory controller. Unbuffered memory is not as stable as buffered memory, but is faster and cheaper to implement. While buffered memory may be necessary in some computer systems, such as high-end corporate servers and workstations, where

    • DDR2 SDRAM

      DDR2 SDRAM

      DDR2 SDRAM, an abbreviation for double data rate two synchronous dynamic random access memory, is a type of a random access memory (RAM) commonly used in personal computers and various digital electronics today. This offspring from the SDRAM (synchronous dynamic random access memory), a part of DRAM (dynamic random access memory), is like an evolution

    • SDHC (Secure Digital High Capacity)

      SDHC (Secure Digital High Capacity)

      SDHC stands for Secure Digital High Capacity. It is a format for new memory cards that is based on the 2.00 specification of the SDA (Secure Digital Association).The name Secure Digital is due to their ability to protect copyright, using digital copyright management. This has made these memory cards a favorite choice in the audiovisual

    • DRAM (Dynamic Random Access Memory)

      DRAM (Dynamic Random Access Memory)

      DRAM is Dynamic Random Access Memory. DRAM is the most common form of RAM. When someone says that a computer has "one gigabyte of RAM", what they really mean is that the computer has one gigabyte of DRAM. DRAM is called dynamic because it must constantly be refreshed or it will lose the data which

    • ROM (Read Only Memory)

      ROM (Read Only Memory)

      Read-Only Memory or ROM is an integrated-circuit memory chip that contains configuration data. ROM is commonly called firmware because its programming is fully embedded into the ROM chip. As such, ROM is a hardware and software in one. Because data is fully incorporated at the ROM chip’s manufacture, data stored can neither be erased nor

    • PROM (Programmable Read Only Memory)

      PROM (Programmable Read Only Memory)

      PROM stands for Programmable Read-Only Memory. It was invented by Wen Tsing Chow in 1956. Unlike a ROM chip, a PROM chip comes from the manufacturers devoid of any programming. Programming is done by the end user or the makers of electronic devices which require a permanent data storage device. Since it is cheaper than

    • How to Test Memory

      How to Test Memory

      When something begins to go wrong with a computer and things start acting differently than they should, the first thing to test should be the computer’s memory. Problems, even small ones, in the computer’s memory can lead to very erratic behavior from the computer, even causing it to crash. Memory Testing Software Memtest86 is our

    • CAS Latency

      CAS Latency

      CAS latency is short for Column Address Strobe latency. CAS latency is the time (in clock cycles) required to access a column of memory on a DRAM memory module. A CAS3 rated memory module requires 3 clock cycles to address a column of memory, where a CAS2 rated memory module can accomplish the same task

    • What is a Hypervisor?

      What is a Hypervisor?

      A hypervisor is a virtualization technique that runs multiple operating systems on the device. While non-hypervisor virtualization techniques run multiple operating systems on domestic computers and hand-held devices, hypervisors are used exclusively on devices whose sole task is to run multiple guest operating systems for commercial or industrial purposes. Hypervisors are used in gaming technologies,
