How long can a new battery maintain the contents of SRAM memory?

• A. One Year
• B. Four Years
• C. Two Years
• D. Five Years

Answer: (B)

The correct answer, four years, is based on the typical lifespan of a new battery in maintaining the contents of SRAM (Static Random Access Memory) memory. SRAM retains data as long as it has power, which is provided by a backup battery when the main power supply is off. In general, new batteries are designed to provide a reliable power source for an extended period, and manufacturers usually indicate an operational lifespan that can vary depending on factors like temperature and usage conditions. SRAM is crucial in systems that require rapid access and retention of data without refreshing, so ensuring that a battery lasts long enough to maintain memory contents is vital. The four-year timeframe represents a balance between reliability and practicality, effectively covering a significant period for typical operational setups before a battery replacement is needed. This allows adequate time for maintenance without risking loss of critical data. The other durations listed are shorter than what is generally expected for a new battery's operational life in this context, making four years the most appropriate and standard choice.
