Today I learned the #nordicsemi #nrf54L series does not use flash memory. Instead program code runs from non-volatile resistive RAM (RRAM). Among other claimed benefits, RRAM is supposed to consume less power "especially during write operations", which would imply it requires less power to *read* as well.
