Abstract
A Flash memory system is implemented in a system-in-package (SIP) enclosure, the system comprising a Flash memory controller and a plurality Flash memory devices. An SIP relates to a single package or module comprising a number of integrated circuits (chips). The Flash memory controller is configured to interface with an external system and a plurality of memory devices within the SIP. The memory devices are configured in a daisy chain cascade arrangement, controlled by the Flash memory controller through commands transmitted through the daisy chain cascade.
