ABSTRACT:
Disclosed is a multi-chip package having a plurality of memory chips. Each memory chip includes a memory cell array storing e-fuse data, a read-out control circuit reading e-fuse data in response to a read signal, a first internal pad receiving a first control signal, a read-out controller generating the read signal to define a read period, and to generate a second control signal following the read period, and a second internal pad receiving the second control signal, wherein the plurality of memory chips is connected series and each respective read-out control circuit and read-out controller in each one of the plurality of memory chips cooperate to implement a sequential read of e-fuse data across the plurality of memory chips.
