# How do they integrate logic into a DRAM process while manufacturing SDRAM?

When SDRAM is manufactured, how do they integrate logic into the IC while they are using a DRAM process for fabrication?
Because SDRAM requires logic to decode its inputs, do the burst ordering, etc. (DRAM too - though it has less logic)

• Why do you think this would be a problem? Regular DRAM has that kind of logic, too. – Dave Tweed Dec 10 '12 at 5:02
• But I still don't get how they integrate logic into a DRAM process - I've read a CMOS VLSI book, and it says it's not possible to put logic on a DRAM process. – Saad Dec 10 '12 at 5:14
