now we have products which have 4 RAM blocks, there is still no functions to access RAMONB as per SDK8.1, but I have created a task and this may be added in the next release devzone.nordicsemi.com/.../

Hi,

The field "RAMONB" is something added for future products/revision, and is not in use at this moment (or even existing). I've reported this internally.

The sd_power_ramon_* functions are directly mapped to the NRF_POWER->RAMON register, meaning that if you set sd_power_ramon_set(0x00030003); you will keep all RAM blocks powered in both SYSTEMON and SYSTEMOFF mode.

As you've already noticed, the nRF51822 only has 2 RAM blocks.

The Reference manual describes the nRF51-series, while each product specification sets restrictions on that specific part. In this case, the nRF51-series is described to have 4 RAM blocks, while the nRF51x22 parts only has two as described in the PS chapter 3.2.2.
