Semiconductor device including option pads for determining an operating structure thereof, and a system having the same

摘要

A semiconductor device includes a memory cell array, pad groups, a first option pad, a second option pad and a data input multiplexer block configured to transmit data, input through all or part of the pad groups, to the memory cell array based on whether the first option pad and a ground are connected to each other, wherein the data input multiplexer block is configured to select first pad groups among the pad groups or second pad groups among the pad groups as the part of the pad groups based on whether the second option pad and the ground are connected to each other.

1. A semiconductor device, comprising:
a memory cell array; pad groups; a first option pad and a second option pad; a data input multiplexer block configured to transmit data, input through all or part of the pad groups, to the memory cell array based on whether the first option pad and a ground are connected to each other; data input buffer groups each connected to one of the pad groups; data strobe pad groups; data strobe input buffer groups each connected to one of the data strobe pad groups; and data input latch groups each connected between one of the data input buffer groups and the data input multiplexer block, wherein the data input multiplexer block is configured to select first pad groups among the pad groups or second pad groups among the pad groups as the part of the pad groups based on whether the second option pad and the ground are connected to each other, each of the data input buffer groups is configured to be enabled or disabled according to whether the first option pad and the ground are connected to each other and whether the second option pad and the ground are connected to each other, each of the data strobe input buffer groups is configured to be enabled or disabled according to whether the first option pad and the ground are connected to each other and whether the second option pad and the ground are connected to each other, each of the data input latch groups is configured to operate based on output signals of the data strobe input buffer group to which it is connected.
