Did RPF change the RAM on Pi Zero?

Tue Feb 18, 2020 11:18 am

The title might sound a little misleading, so I'll clarify right away: The RAM capacity has not changed (and is technically limited by the CPU IIRC).

I recently ordered a Pi Zero from Pimoroni and was a little surprised that it looked a little different than all the others I'd seen before: It seems like it's using a RAM chip from Micron instead of ELPIDA.

I know this is completely irrelevant technically, but I still found it interesting :geek: :)

Did anyone else get a Pi Zero that uses a Micron RAM chip? What other variants of the Pi Zero (beyond the W(H)) do you know?

I guess the pricing on RAM has changed a bit. The original Pi 1B used a variety of RAM chips, including Micron, so the BCM2835 firmware is already configured for those.

All of my Pi Zeros seem to have Elpida chips on, but I haven't bought any new ones for a while.

There are only 3 variants of the Zero

$ 5 Zero
$10 Zero W
$15 Zero WH
The information is out there....you just have to let it in.

Elpida Memory went bankrupt and was acquired by Micron, easily explaining the switch from Elpida to Micron branded RAM.

Thanks! Sorry, seems like I missed that thread.
I know of these three Pi Zero variants, meant to write build variants, i.e. different components (such as RAM), maybe PCB color, this sort of thing :D .

Good find! Totally makes sense!

All Zeros are manufactured at Sony UK for the worldwide market, so all green PCB. Though other components could be sourced from other manufacturers to lower the BoM cost.
