Abstract
A phase change memory may be organized with a global word line coupled to a plurality of blocks, each with a plurality of phase change memory cells arranged in rows and columns. Thus, one global word line may be common to a plurality of blocks. The global word line may be coupled to a word line decoder that is responsible for pulling the word line to ground. Each of the blocks, on the other hand, is coupled to a bitline selector through a bitline. Each block may have its own local word line coupled to the global word line. In some cases, this architecture reduces the minimum capacity of the memory.
