The following chips can be found on Kingston DDR-RAM DDR 333, 400 modules.
For more information on which modules you can find these chips follow this link.
D328DW-50 = Winbond BH-5
D328DW-60 = Winbond BH-6
D328DW-45
Before 0318 BH-5
In 0319 BH-5/CH-5
After 0319 CH-5
Same Chips, but less legs than the genuine Winbond Chips?
Kingston's relabeled BH-5 / BH-6 and CH-5 chips (D328DW - 45, 50, 60) have twelve legs less than the orginal BH-5/BH-6 and CH-5 chips.
Those chips that Kingston used are custom made by Winbond.
Orginal Winbond BH-5 / BH-6 and CH-5 chips have 17 dummy (no connection) legs. Kingston wanted chips without most of them. (less traces, cheaper PCB), and Winbond made custom chips for Kingston. Winbond removed twelve legs from the original chip and used a different pin out. They still left five dummy legs on those custom chips, because they wanted an even amount of legs on each side of the chip.
Not connected legs in original BH-5 / BH-6 and CH-5 chips are:
4, 7, 10, 13, 14, 16, 17, 19, 20, 25, 43, 50, 53, 54, 57, 60, 63.
Those custom chips are also the reason why Kingston still has "some" certain sticks with BH-5/BH-6 chips on their shelves.
