Digital ICs/DSP: Micro-DIMMs Shave 35% Off The Space SO-DIMMs Need

The DDR2 Micro-DIMM modules for Sub-Notebooks are only 65% of the size of equal capacity small-outline dual-inline memory modules (SO-DIMMs) used for notebook computers. The Micro-DIMMs' 214-pin "mezzanine connector" reduces the size of the module and the area the connector covers by about 40% compared to standard SO-DIMMs. Available with capacities of 256, 512, and 1024 Mbytes, Micro-DIMMs are implemented with the company's single-die 512-Mbit or 1-Gbit DDR2 memories, which are housed in fine-pitch BGA packages. Samples are available in PC2-3200 and PC2-4300 speed grades. The 256-Mbyte Micro-DIMMs sell for between $80 and $100, and the 512-Mbyte versions go for $150 to $170. Prices for the 1-Gbyte units are available on request.
