The PCM MCP s a 56 ball FBGA package, and has a package dimension of 9.2 mm (length) x 8.2 mm (width) x 1.1 mm (thick). Side view X-ray analysis of the K571229ACM PCM package, shown in Figure 2, reveals that the PCM MCP is a 512 Mbit PCM die co-packaged with a 128 Mbit UTRAM (8M x 16).
Phase change memory (PCM) combines the nonvolatile attributes of flash memory like NOR and NAND types, bit alterability, and fast read and write of RAM or EEPROM. This positions PCM to potentially provide memory solutions in the memory subsystems of cellular phones, PCs, and embedded and consumer electronics applications. Numonyx (now Micron) has previously demonstrated a NOR compatible PCM for commercial applications. Samsung is another major player who announced, in 2010, a NOR compatible PCM for mobile device applications.
