SanDisk said Monday that it is shipping memory chips that will allow consumers to store more data on tiny Secure Digital flash cards.

The Milpitas, Calif., company’s X4 technology packs four bits of data into each memory cell. To date, flash memory chipmakers typically stored one bit or two bits per cell. Each individual die–or chip–holds 64 gigabits of data, or 8 gigabytes. This is the highest capacity per die in the industry, according to SanDisk.

The technology is shipping now in 8GB and 16GB SDHC (Secure Digital High Capacity) cards as well as 8GB and 16GB Memory Stick PRO Duo cards, the company said.

Future technology will ultimately yield tiny Secure Digital (SD) flash cards that hold 64GB of data and larger capacities. Currently, mainstream SanDisk SD cards top out at 32GB.

The memory technology itself–the 4 bits per cell 64-gigabit memory–is codeveloped and co-owned by SanDisk and Toshiba. The X4 controller technology is solely owned by SanDisk.
