As the world demands faster and higher performance in every application, new memory technology is needed to enable smarter solutions. FRAM from Texas Instruments provides unified memory with dynamic partitioning and memory access speeds 100 times faster than flash.
FRAM is also capable of zero power state retention in all power modes, which means that writes are guaranteed, even in the event of a power loss. And with a write endurance of over 100 trillion cycles, EEPROM is no longer required. All of this is possible at less than 100μA/MHz active power consumption – a first for the semiconductor industry.
MSP430 devices with embedded FRAM are cutting the industry’s best active power consumption by half, achieving sub-100μA/MHz. Read and writes require just 1.5V, so it is able to operate without a charge pump, unlike Flash and EEPROM. This lowers power and minimizes physical footprint.
Both writing to memory at 12kB/s
Summary: At equal throughput, FRAM consumes 250x less power than Flash
FRAM is uniquely flexible offering developers the ability to use the same memory block to function as program memory or data memory. With FRAM, developers can dynamically partition the memory depending on the current stage of the user’s development cycle.
This feature allows faster time to market and simplified inventory control – one single device can be dynamically configured into various memory configurations.
In addition to lower power performance, FRAM can also maintain unmatched data throughput. MSP430 with embedded FRAM is capable of 50ns access times, enabling speeds up to 1400 kB/s. With FRAM, embedded memory is no longer the bottle neck of your application.
Summary: FRAM maximum throughput is >100x faster than Flash maximum throughput, while still consuming 3x lower power than Flash
Embedded FRAM also offers longetivity and endurance that existing memory technologies cannot match. FRAM offers virtually unlimited endurance at 1015 cycles. This increased write endurance is particularly ideal for datalogging, digital rights management, battery-backed SRAM and other applications.
Summary: FRAM's increased write endurance enables 10,000,000,000x longer memory life cycles than Flash
FRAM offers additional security and robustness compared to existing Flash and EEPROM technologies. Since FRAM is crystal-based, rather than charge-based, its Terrestrial Soft Error Rate is below detection limits and is not susceptible to radiation.
Additionally its ultra-low power requirements and high speed make FRAM data reads and writes virtually undetectable to unauthorized sniffing or data profiling.
