256 Kb parallel F-RAM

16 September 2009 DSP, Micros & Memory

Ramtron has launched its second parallel device in a family of new parallel and serial F-RAM products that offer high-speed read/write performance and low-voltage operation. The latest device in the V-Family is the FM28V020, a 256 Kb, 2,0 to 3,6 V, parallel non-volatile RAM in an industry standard 28-pin SOIC package. It is a 32 K x 8 device that reads and writes like a standard SRAM and retains data for over 10 years after power is removed. In-system operation of the FM28V020 is similar to other RAM devices, allowing it to be used as a drop-in replacement for standard SRAM. Read and write cycles may be triggered by toggling a chip enable pin or by simply changing the address. F-RAM memory is non-volatile due to its unique ferroelectric memory process, making it ideal for non-volatile memory applications that require frequent or rapid writes. The device operates over the full industrial temperature range of -40°C to +85°C.
