A type of memory specification once championed by Intel that uses a 16-18 bit bus width to transfer data up to speeds of 1066MHz, making it much faster than SDRAM. Despite its inherent performance advantages it has declined in popularity in recent years and is far less prevalent than its major competitor, DDR.

A piece of circuitry on a memory module that sends information about the module to the system, such as speed, size and bank information.

Memory designed for a specific system or motherboard. Proprietary memory may be patented.

Synchronous DRAM’s transfer data in
lock step with the rising edge of an applied square wave shaped clock signal (the same clock signal that operates the memory controlling chip set). Since the timing of synchronous DRAM is very predictable, data can be transferred at a much higher rate than was possible with older technologies such as [...]

To fill a memory socket, either with a true module or with something that completes the circuit, such as a C-RIMM. An empty socket is referred to as unpopulated.

A board made of fiberglass and electrical traces, to which chips and sockets can be attached. PCBs are used with memory, motherboard, graphics cards and many other types of devices.

An SDRAM speed used with 133MHz FSB systems. PC133 memory can be used in PC100 systems, as memory is backwards-compatible with regard to speed, but it will only operate as PC100. There are some exceptions to this backwards compatibility rule due to system or BIOS restrictions.

Yes, only if you have a 100 MHz system bus. No ,if you have a 66 MHz system bus. On certain system, a non-PC100 module may be “pushed” to run in a 100 MHz system, but the results are not guaranteed and may lead to system instability.

Memory that uses extra chips (known as registers) to delay data passing through it to allow more time for proper transfer. This allows for more memory chips on the module and can protect data integrity. Registered and unregistered memory cannot be mixed in the same system, and many systems cannot use registered memory. System owners [...]

An SDRAM speed used with 100MHz FSB systems. Runs at a clock speed of 100MHz.
