#85162 - SDRAM controller Responding to: ???'s previous message |
Jez Smith said:
sorry about getting here late but I did do a sdram controler design which would be suitable to handle all the nasty refresh timing you need if you are going to use sdram or similar Hmm, on what kind of hardware is the controller based and what kind of SDRAM is it designed for? And is it designed such that it could be used for MOVX-type interface to the 8052? I had come to the conclusion that 512k x 4 would be the easiest solution and it would certainly provide enough memory for my minimum and typical needs--but if SDRAM could be implemented with a single IC and a standard SIMM or DIMM then that'd be nice since it'd use more commercially-available RAM modules and take up less board space than 4 512k RAMs plus address decoder.

| SDRAM maybe viable | 01/01/70 00:00 | |
| What about pseudo static ram? | 01/01/70 00:00 | |
