Abstract
Methods to generate an accurate reference current by
averaging multi-pair dummy cells’ c urrents for distinguishing the
data in sense ampli fiers (S/As) of a large scale memory with resis-
tance change cell is presented and analyzed. The predicted charac-
teristics are con firmed by comparing them with measurement re-
sults of the functionalities and the retention time distributions in a
floating body random access memory (FBRAM). The methods are
found to be especially effective in s ituations wher
