| ||
| Form Factor: | The form factor of any memory module describes its size and pin configuration. Most computer systems have memory sockets that can accept only one form factor. | ||
| Your choices are... | |||
| DIMM | Dual in-line memory module (DIMM) provides a 64-bit data path. DIMMs can perform the functions of two single in-line memory modules (SIMMs). Typically, Pentium® processors use a single DIMM instead of two SIMMs. Pentium is a registered trademark of Intel Corporation. | ||
| SO DIMM | Small outline, dual In-line memory modules (SO DIMM) are enhanced versions of standard DIMM. SO DIMMs are about half the length of a typical 72-pin SIMM. These compact DIMMs are used in mobile computing devices. SO DIMMs come in a variety of pin sizes and can be installed either singly to support 32-bit systems, or in pairs to support 64-bit systems. | ||
| uDIMM | Micro single inline memory module (uDIMM). | ||
| AIMM | Accelerated (or advanced) graphics ports (AGP) in-line memory modules (AIMM) allow the graphics controller to directly access texture map data from the main memory rather than having to move it to the graphic controllers' local memory first. This helps increase system speed for processing graphics and allows for a use of a larger portion of memory by "borrowing" storage for texture maps from main memory. | ||
| RIMM | Rambus inline memory modules (RIMM) are designed to install Rambus DRAM (RDRAM). | ||
| SO RIMM | Small outline Rambus inline memory modules (SORIMM) have a smaller profile that standard RIMMs and are used in laptop computers and systems that have strict size requirements. | ||
| SIMM | Single in-line memory module (SIMM) provides a 32-bit data path. Devices that require wider data paths, such as Pentium® processors, use a pair of SIMMs. Slower processors use a single SIMM. Pentium is a registered trademark of Intel Corporation. | ||
| Card | The memory is in a card configuration. | ||
| Other | Other unlisted form factor. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Timing | |||
| Your choices are... | |||
| Asynchronous SRAM | Asynchronous static RAM (SRAM) is not synchronized with the system clock. It is slower than synchronous SRAM. | ||
| Synchronous SRAM | Synchronous SRAM is synchronized with the system clock. It is faster than asynchronous SRAM and provides speeds up to about 8.5 ns. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Technology | |||
| Your choices are... | |||
| DDR | In double data rate (DDR), memory transfers data on both edges of the clock. | ||
| QDR | Quad data rate (QDR) uses two ports to independently run at double data rate (DDR); the net result is four data items per clock cycle. | ||
| QDR-II | Quad data rate, type II (QDR-II). | ||
| ZBT | Zero bus turnaround (ZBT) is a synchronous SRAM architecture optimized for networking and telecommunications applications. It can increase the internal bandwidth of a switch fabric when compared to standard Sync Burst SRAM. ZBT SRAMs became the de facto industry standard for these applications when they were introduced, much like synchronous burst SRAMs are the industry standard in the PC cache market. | ||
| Other | Other unlisted, specialized or proprietary SRAM Technology. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
| ||
| Capacity: | The amount of data that can be transmitted over a specific period of time. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Clock Speed: | Clock speed is the raw MHz that the CPU (Central Processor Unit) operates at. For example, an AMD Athlon 1GHz has an operating clock speed of 1000 MHz; this is the processor's clock speed. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
