HP Announces Tiny Wireless Memory Chip 137
Hewlett-Packard researchers have developed a memory chip with wireless networking capabilities that is roughly the same size as a grain of rice, the company said Monday.
Prototypes of the Memory Spot chip developed by HP Labs contain 256 kilobits to 4 megabits of memory and can transfer data wirelessly at speeds up to 10Mbps. There are eight bits in a byte. This amount of storage allows the chips to hold a short video clip, digital pictures or "dozens of pages" of text, HP said, adding that the chips do not require a battery.
Memory Spot chips get their power using a technique called inductive coupling, which allows power to be transferred from one component to another through a shared electromagnetic field. In the case of Memory Spot, this power is supplied by the device that is used to read and write data on the chip.
Data stored on Memory Spot chips could be accessed using a variety of devices, such as specially equipped cell phones or PDAs, making them suitable for a range of applications, such as adhesive attachments applied to a paper document or printed photograph, HP said.

As for bytes not being an SI unit, well, it doesn't really matter since "kilo" always means 1000 for those using metric. People don't care wether "bytes" is part of SI units or not. It is, as you said yourself, overloaded. To most people, one kilo = 1000 units, whatever the units are. Except for programmers, but most people aren't programmers.

Not all bytes have 8 bits. A lot of older mainframes have 7 -- that's why octal was popular once, and why UTF-7 is still widely used. A few had 9, although that wasn't widespread. Some specialized computing devices have anywhere from 5 to 10. So pointing out that it's 8, in the context of a whole new specialized chip, isn't redundant.

Eight bits in a byte? When did this happen?
I think the size of a byte became exactly eight bits in the 60s, though it's possible that other-sized bytes existed in machines developed into the 70s. These days the term is pretty unambiguous, but telecommunications standard documents usually prefer the term 'octet', since there have been bytes of other sizes (and even platforms with *variable-sized* bytes). In particular, 6-bit bytes were very common early in computing history.

Apparently 6-bit or 9-bit bytes and 36-bit words were common in the early days of computing because it was close the the minimum number of bits (35) needed to represent a number out to 10 significant digits (for scientific computing).

RFID features longer range and a small uniform, pre-encoded response. (e.g. ID Badge at work) HP's new chip features shorter range and a larger response, selectable from a large pool of responses, and probably the pool of responses is changeable even after deployment.
As another poster said, the short ranges at which this thing would work will alleviate a lot of people's privacy concerns. Still I gotta say that tagging people is still tagging people.
