The technology is called “bit-serial ID” because it is based on the fact that there are eight bits in a byte. The example was given of serial number A20000. This is a 32-bit number but with a lot of zeros in the end to make it easier to read. To read the complete number the reader will take the first 32-bit of this serial number and put this 32-bit part in the left and right RAMs in parallel. These two bits will be the first two bytes, so to make things more obvious the reader will read the bits 0 and 1 into the left and right RAMs in parallel and then the reader will read the next bits which are 2 and 3. The reader will put these two bits in the left and right RAMs and the reader will continue in this fashion until it reads the last 32 bits which are the first 8 bits of the serial number A20000.
If the whole number is not a multiple of 8 bits, a reader will take the left RAM in a manner similar to this one. To do so, the reader will start at the left RAM and first read the first 8 bits of the number and store this bit pattern in the left RAM. Then the reader will move to the right RAM and start to read the next 8 bits of the number and store them in the right RAM. The reader will continue until it has read all the bits that are in the number and will then move to the next 32-bit number.
Summary
I will close this article with a summary of the bits of information that I have mentioned in this article.
Design of Memory
Bits are the smallest components of computer systems
Bits are the smallest components of memory
A bit is a unit of data that is represented by one or more physical signals (ones and zeros)
A word of memory (on a RAM) is made up of 32 bits
The size of a word can vary from 1 bit up to 8 bits (byte)
Memory is a type of computer storage medium, which is used to store data
RAM is short for Random Access Memory
Memory is the place where programs, data and information are stored
Memory is a combination of hardware and software
Memory is the capacity to temporarily store information
Memory is the hardware part of a computer or microprocessor
Bits are used in the construction of the memory
