Designs that require both nonvolatility through power-down events and the fast random access of SRAMs will often include batteries to hold the SRAM VDD level up when system power is lost. Cypress offers a range of F-RAM and nvSRAM devices in different densities that are pin-compatible with industry-standard SRAMs and which solve this problem without requiring batteries. These two technologies, F-RAM and nvSRAM, have different values and characteristics; please contact Cypress for a discussion on which nonvolatile products best fit your applications.
