Samsung has developed a 4GB chipset which it claims obviates the need for memory expansion slots in space-starved mobile phones.
The Samsung moviMCP is implemented on a 4GB embedded memory card, comprising two 16Gb Nand Flash chips and controller, 1Gb mobile DRam chip to support the processor and 2Gb Nand Flash memory for general handset operation.
This provides a total memory capacity of a little over 4GB. The design is currently being sampled by phone makers.
Samsung has used the eMMC interface (the MultiMediaCard Association standard for embedded memory) to simplify the management of the various types of Nand Flash.
The design stacks several memory functions vertically further reducing the footprint.
