LPDDR2 stands for Low Power Double Data Rate 2, a type of memory used primarily in mobile devices like smartphones and tablets. It is designed to consume less power while providing faster data transfer rates compared to its predecessor, LPDDR. This efficiency helps extend battery life, making it ideal for portable electronics. Introduced in 2010, LPDDR2 supports a data rate of up to 1066 MT/s (megatransfers per second) and operates at a lower voltage, typically around 1.2 volts. This technology has been widely adopted in various devices, contributing to improved performance and energy efficiency in mobile computing.
