Methods and apparatuses including a global timing generator and local control circuits

摘要

Apparatus and methods are disclosed, such as a global timing generator coupled to local control circuits. Each local control circuit can control programming and reading of a memory element in a tile of memory elements in an array responsive to a timing signal(s) from the global timing generator. Additional apparatus and methods are described.

1. An apparatus comprising:
a global timing generator; and a plurality of local control circuits, each local control circuit including
a circuit to compare a sensed state of a memory element with external data; anda pulse generator coupled to the global timing generator, the pulse generator to program the memory element responsive to a timing signal from the global timing generator if the sensed state is not the same as the external data, the pulse generator comprising:
a first pulse reference signal source, coupled to the memory element through a first transistor circuit, to generate a voltage signal to program a first state into the memory element in response to the timing signal; anda second pulse reference signal source, coupled to the memory element through a second transistor circuit, to generate a voltage signal to program a second state that is an inverse of the first state, into the memory element in response to the timing signal.
