A COMPOSITE MEMORY HAVING A BRIDGING DEVICE FOR CONNECTING DISCRETE MEMORY DEVICES TO A SYSTEM

摘要

A composite memory device including discrete memory devices and a bridge device for controlling the discrete memory devices in response to global memory control signals having a format or protocol that is incompatible with the memory devices. The discrete memory devices can be commercial off-the-shelf memory devices or custom memory devices which respond to native, or local memory control signals. The global and local memory control signals include commands and command signals each having different formats. The composite memory device includes a system in package including the semiconductor dies of the discrete memory devices and the bridge device, or can include a printed circuit board having packaged discrete memory devices and a packaged bridge device mounted thereto.
