Power-Management ICs Are Ideal For DDR-SDRAM MeMORIES

摘要

Switching-type voltage regulation is the way to go, but don't forget to consider static, transient, and standby operating modes. Double-data-rate, single-data random access memory (DDR-SDRAM) has become popular in desktop and portable computing. The reason is its superior performance, low power dissipation, and competitive cost compared to other memory technologies. DDR initially had a 266-Mbyte/s data rate versus a 133-Mbyte/s data rate for plain SDRAM. Subsequently, the DDR data rate has increased to 400 Mbytes/s. A second-generation DDR, or DDR2, debuted at the beginning of 2004. This extended the data rate from 400 up to 667 Mbytes/s, while reducing power consumption further.
