Kingston is ahead of the pack by a wide margin, recording total DRam module sales of more than $2.2bn in 2006, nearly $800m more than in 2005.
The 2006 total represented a market share rise to 18.1 per cent, over three times that of its closest competitor, Smart Modular Technologies, which had a market share of 5.5 per cent.
"To be number one on iSuppli's list is exciting and humbling, especially as Kingston turns 20 years old later this year," said Kingston co-founder David Sun.
"Our growth could only have been accomplished through the loyalty and support of our employees, customers and vendors."
Founded in 1987 with a single product, Kingston now offers more than 2,000 memory lines.
In addition to Flash memory for the latest digital devices, Kingston's DRam module offerings include branded or system-specific memory.
The company also provides ValueRAM memory built to Jedec specs and designed for system integrators and white box builders, and HyperX for gamers and PC enthusiasts who demand higher performance and speed.
The iSuppli report encompassed DRam module revenues only, and did not include OEM contract manufacturing or Flash memory sales.
Kingston announced in February that its 2006 revenues were the highest in its history, as global sales reached $3.7bn.
