Tiny memory cards have meant fast growth for Sunnyvale, Calif.-based
That explosive growth helped put Chief Executive
When Harari founded SanDisk in 1988, nobody took baby pictures with digital cameras. Although camera makers like
Harari, who has a Ph.D. in solid-state physics from Princeton University, was among those who saw that a technology called flash memory might do the job. Flash is a cousin of the random access memory (RAM) used in personal computers; but unlike RAM, which is erased when a computer is turned off, flash continues to keep what's stored on the device after the power is turned off. Harari believed the silicon-based technology could become small enough to be the digital equivalent of Kodacolor or Fujifilm.
The technical obstacles to making small memory cards daunted most venture capitalists. "They said you couldn't do it with today's technology," Harari says. They had a point. SanDisk's first product, sold in 1990, was a flash memory disk that IBM

These days, SanDisk crams 1.2 gigabytes of memory onto its tiny disks, all of it stored on transistors or switches that store information by being on and off. Unlike RAM, in flash these switches hold their positions even when no electricity courses through them, holding memory until the user decides to erase it.
But the sun may not always shine so brightly on SanDisk. The 720-employee firm's ascent was fueled by an explosion in the use of flash memory. In 2000, sales of flash-related products were up 133% to $10.6 billion, says Brian Matas, vice president of IC Insights, a semiconductor market research firm. SanDisk is only a small meteor in that storm.
SanDisk is now a leader in selling flash applications to consumers, although consumer sales represent a small portion of the entire market for flash products, says Matas. Hewlett-Packard
In addition, the consumer market is as volatile as RAM and is sensitive to economic downturns. And although Harari says that he's not worried about flash media disks becoming commoditized yet, they are bound to become so as they become more ubiquitious.
For the three months ended March 31, Sandisk's revenue decreased 7% to $101.3 million. The fortuitous wave that landed Harari atop our list may have already crested.
