Researchers from the University of Southern California School of Engineering have developed a new type of memory that actually puts a processor on the DRAM chip, allowing for significantly faster memory performance and eliminating the gap between CPU and memory performance. The memory, called Data IntensiVe Architecture (DIVA), is a Processor in Memory (PIM) chip that contains four processors per memory chip, each capable of performing an 8-bit, 16-bit or 32-bit mathematical process.

The thing I've thought for years I'd like to see would be a DRAM with a few rows' worth of buffering. In a DRAM chip, a row of data (I don't know how many bits that's up to these days, but many thousands) is read at once from the main array, and individual bits, bytes, or words (depending upon chip organization) are read out. Since the slowest operation is reading the data from the array into the row buffer, a chip with multiple row buffers would have an effective cache that could be filled much more quickly than a conventional cache.

I got to learn more about memory architectures.

MUch more to it .
