Abstract
The invention relates to methods and systems for reading a memory cell and in particular, an STT MRAM. In accordance with one aspect of the invention, a system for reading a memory cell includes a read path and a precharge path. The reference current is provided through the read path and is sampled via a sampling element in the read path. Subsequently, a current from the memory cell is provided through the same sampling element and read path. The output level is then determined by the cell current working against the sampled reference current.
