Abstract
Embodiments include systems, methods, and apparatuses for reading a data signal from a memory, such as a dynamic random access memory (DRAM). In one embodiment, a memory receiver may include a differential amplifier to receive a data signal from the memory and pass a differential output signal based on a voltage difference between the data signal and a reference voltage. The data signal may have a first direct current (DC) average voltage level, and the differential amplifier may shift the differential output signal to a second DC average voltage level that is substantially constant over a range of values of the first DC average voltage level. In another embodiment, a voltage offset compensation (VOC) circuit may apply a compensation voltage to the output signal that is based on an activated rank or an identity of the memory module. Other embodiments may be described and claimed.
