An important motivation for Timna to use RDRam could be the memory granularity issue. For very low-end systems, like those addressed by Timna, the base system cost must be minimal. So the minimum memory size for the system is important.

If one assumes 256Mb memory chips in a "16-bit wide" configuration, a system would need 4 chips which results in a minimum memory size of 128MByte. RDram would only need one 256Mb chip resulting in a minimum memory size of 32MByte.

The system manufacturers could go to less dense chips. But after 256Mb chips reach serious production, the cost per bit of the less dense chips will be higher. Likewise the industry has shunned 32bit wide chip configurations. This issue becomes worse when 1Gb chips come out.
