Battery-free 4Mbit FRAM serves as viable SRAM alternative

Fujitsu Semiconductor America has developed a battery-free alternative to static random access memory in equipment such as medical devices, office tools and industrial machinery. The MB85R4M2T is a 4Mbit ferroelectric RAM chip encased in a 44-pin thin small-outline package, requiring less space on PCB boards. The company expects to launch sample quantities of the product in January 2014.

Because no battery is required, the new MB85R4M2T can reduce the mounting area for memory and related components on PCB boards by at least 50 per cent. This also cuts the cost of parts and maintenance, lowering total cost of ownership. The MB85R4M2T allows random access, so developers can make use of any part of the memory bank easily, as required. The fast writing speed minimises the data loss in cases of power failure.

Unlike SRAM, which requires 15 microwatt per-second power current to retain data in memory when the main power is off, non-volatile FRAM products like the MB85R4M2T consume zero electricity, significantly lowering power consumption for data retention. The 4Mbit MB85R4M2T's 44-pin TSOP package and parallel interface are compatible with standard SRAM memories, so the chip can substitute for SRAM in many applications.
