When you say "disable the memory", does it means what's described in the datasheet as "6.5.5. Full Memory Power Down" ?P2350 can use powman to disable the memory modules (getting 1.6 mA). I tried using directly disabling memory (XIP, SRAM0, SRAM1), yet after the timeout the processor is reset (the main method executes from the start), I believe I'm doing something wrong and still not sure what.
In this case a reset is almost always necessary because the fully powered down memory (including XIP cache) is losing it's content, and a wake-up without full reset can only lead to a crash in most of the cases when using SDK.
Keep in mind that on Pico2W there are other components which can still consume power if not properly shut shown, like the WLAN module.
Also the SMPS can back-power or leak some currents from 3.3V even when bypassed.
