I got a chance to look inside a Transcend PSD330 32GB. It had a Silicon Motion SM2236G Compact Flash controller.

The SM2236 is the world’s highest performance and the lowest power consumption CompactFlash card controller. Fully compliant with CFA 6.0, the controller supports UDMA transfer on true-IDE and PCMCIA modes, especially designed for professional DSLR. The SM2236’s ECC can support most major NAND flash vendor’s new generation MLC/SLC NAND and perform global wear-leveling to evenly distribute the write and erase counts to each block. Incorporating the advanced ECC and global wear-leveling algorithm, the SM2236 can operate with various NAND flash memories/process geometries and maximize the life expectancy of CompactFlash card.
