4GB DDR2-400

Column Address Strobe (CAS) latency, or CL, is the delay time between the moment a memory controller tells the memory module to access a particular memory column on a RAM module, and the moment the data from the given array location is available on the module's output pins. In general, the lower the CAS latency, the better.

A computer's memory which is directly accessible to the CPU.

How the overall memory of the product is put together, defined by the number of modules and the size.

The type of internal memory such as RAM, GDDR5.

The frequency at which the memory (e.g. RAM) runs.

Design of the memory e.g. 240-pin DIMM, SO-DIMM.

ECC means Error Correction Code, and it is memory that is able to detect and correct some memory errors without user intervention.

The voltage (V) of the memory in the device.
