Memory Issues:Cost 
 
 
Cost primarily an issue for low to mid range boards intended for consumers
Would like to use standard DRAM for memory because:
- offers highest density at lowest cost
- High volume of standard DRAM also means low cost
 
 - BUT…. will performance will suffer because it only has one port?
- Newer single port Synchronous DRAMs have enough performance for both 2D & 3D apps
