What needs more than half a gig? The 4S copes. Going up to 1GB adds an unnecessary $9 to the BOM which eats into margins.

- masklinn 15y agoBiggest issue with more RAM is not money so much as battery capacity: it's very hard to gate RAM, so more ram means more transistors which are very hard to shut down, meaning lower battery capacity. And a higher surface area and more heat (assuming the manufacturing process is constant). On a mobile device, more RAM is often a balancing act.
- rbanffy 15y agoWould be nice if we could power down unused memory regions... Sounds easy to implement - a "this block is unused" line on the memory chip that would power down the block pointed to by the address bus. Any write to that region would automatically power it back on. Latency on the first write could be a problem unless we could cache writes (L4-cache within the memory module, perhaps? don't we already do something like it?)
- recoiledsnake 15y agoThe power up/down logic, hardware and individual power wiring could consume enough power and hardware to render the savings useless.
- rbanffy 15y agoI wonder if someone actually tried it.
