1. A semiconductor storage device, comprising:
- a storage element to store a data state;
an isolation circuit coupled to the storage element comprising an output derived by the stored data state;
a first access device coupled to the storage element and further coupled to a first access circuit to read or alter the stored data state;
a second access device coupled to the output and further coupled to a second access circuit to read the output state, wherein the isolation circuit prevents the second access circuit alter the stored data state.
