Z-RAM Shrinks Embedded Memory

摘要

Many of today's microprocessors seem like memory chips with embedded logic—their on-chip caches and memories account for most of the transistors and sometimes most of the die. External memory hasn't kept pace with processor speeds, so it's easier to improve performance by slapping down more cache arrays than by designing a more sophisticated processor core. In addition, complex processor cores use more power when they're active, and they leak more current when they're not.
