Batteries

Memory batteries ICs are specialized integrated circuits that combine memory storage with battery power. These ICs are commonly used in applications where memory data needs to be retained even when power is lost, such as in real-time clock (RTC) chips, non-volatile memory (NVM) devices, and various microcontroller and embedded systems.

Memory batteries ICs typically consist of a small rechargeable battery coupled with a low-power SRAM or EEPROM memory array. The battery provides backup power to the memory during power outages, ensuring that critical data is not lost. To minimize power consumption, these ICs use various techniques, including low-power design, sleep modes, and power gating.

Some common examples of memory batteries ICs include Maxim Integrated’s DS1307 RTC chip, Microchip’s 24LC256 EEPROM, and STMicroelectronics’ M48T59Y NVRAM.
