Memory Frames

Frame memory is a virtual view of secondary storage that can be implemented with reasonable overhead to support database record storage and accessing requirements. Frame memory is designed so that its operating characteristics can be easily manipulated by either designers or design algorithms, while performance effects of such changes can be accurately predicted. Automated design procedures exist to generate and evaluate alternative database designs built upon frame memory, and the existence of these procedures establishes frames as an attractive memory management architecture for future database management systems.

The MemoryFrame MF-575 digital picture frame from Digital Spectrum offers a few interesting features, but the overall performance leaves it well behind most other models.

To load photos, you can use a memory card or connect a computer through a USB port, but the MF-575 has no internal memory for storing photos. The MF-575 includes a variety of frame styles and colors for some stylish flexibility. With a 5-3/5-inch diagonal measurement, the MF-575’s screen is smaller than most models. The MF-575 supports only four different types of memory cards. Despite the low street price of about $75, it’s tough to recommend the Digital Spectrum MemoryFrame MF-575.
