Abstract
An apparatus includes a memory array to generate a data eye diagram. The memory array includes a plurality of rows of memory cells. The memory cells include a first row corresponding to a first sampling circuit of a first plurality of sampling circuits. The first sampling circuit is configured to compare an input voltage signal to a first reference voltage. The memory cells also include a second row corresponding to a second sampling circuit of the first plurality of sampling circuits. The second sampling circuit is configured to compare the input voltage signal to a second reference voltage. Each memory cell of the memory array is an incremental multi-bit counter.
