FLASH memory drives come in many odd forms — disguised as plastic sushi pieces, Swiss Army knives and Hello Kitty figures. Now, a contender for the oddest: a vibrator.

An erotic toy with built-in flash memory is the latest addition to a growing, evolving industry. The toy’s maker is Crave, a new San Francisco company begun by a Stanford University designer-engineer whose Duet vibrator started showing up this year in stores like Good Vibrations in San Francisco and Babeland in New York and recently hit a handful of boutique retailers around the country.

The Duet Lux looks like a sleek tuning fork, with a silicone tip and a gold-plated band. Open it up and discover a USB port with 8 gigabytes of memory (for $219), or pay $349 for 16 gigs and a gold-plated base.

The obvious question: Why computer memory? Has multitasking jumped the shark?

Including memory was not Crave’s original intent. The idea was simply that the device’s USB port would be chargeable by computer, eliminating the need for cords or batteries.
