What Is PC133 RAM?
PC133 RAM is a common version of SDRAM (Synchronous Dynamic Random Access Memory). It is a computer memory chip that loses its contents when the power is shut off. It is also an important link in the data access path. Simplified, the path travels from the hard drive to the RAM chip, then to the user interface of the computer.

Terms
-
Access time is a term for the time it takes for the processor in a computer to read its information from memory. A nanosecond (ns) is one billionth of a second. Electricity travels at the rate of one foot per nanosecond.
Features
-
PC133 stands for 133 MHz (megahertz) which is 7.5 ns. This is the measure of access time, and the higher the MHz, the faster the speed.
-
Identification
-
SDRAM chips have two notches where the chip fits into the memory module on the motherboard.
Considerations
-
Companies sell chips usually by size, not by speed. A PC133 RAM comes in several different sizes--128MB, 256MB and 512MB.
History
-
The first PC133 chip was manufactured by Corsair in June 1999.
