https://devzone.nordicsemi.com/f/nordic-q-a/17810/nrf52-ram-retention-vs-ram-powerI&#39;m trying to figure out the RAM power and RAM retention on the nRF52. This is the micro I&#39;ve used that has had the ability to turn chunks of RAM on or off. Here&#39;s my understanding. Retention and power are 2 separate, but somewhat related options.en-USTelligent Community 13Thu, 17 Nov 2016 20:48:49 GMThttps://devzone.nordicsemi.com/thread/68649?ContentTypeID=1Thu, 17 Nov 2016 20:48:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:acf41657-f9f6-4660-bbbc-6914b38eac9cSusheel Nuguru<p>yes, that is correct</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/68648?ContentTypeID=1Thu, 17 Nov 2016 20:28:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f80e5356-5830-4103-8fa1-504f8ec04ac1CurtisHx<p>Gotchya. So powering off a RAM block will cause it to loose its contents.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/68647?ContentTypeID=1Thu, 17 Nov 2016 17:22:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:34db6c79-5901-4672-9e86-23aeae6aef1cSusheel Nuguru<p>RAM rentention will only retain the RAM block contents only in SYSTEMOFF mode. SYSTEMOFF is a deep sleep mode which is different than power down. When system is powered cycled, no matter what the settings for RAM retention are, its contents are lost.</p><div style="clear:both;"></div>
