CUPERTINO, Calif. — Apple says it will sell an iPad with more memory than the current models available.

Apple Inc. said Tuesday that the new, full-size model comes with 128 gigabytes of memory, up from 64 gigabytes. Nothing else has changed, so it will remain a fourth-generation iPad, which went on sale in November. The memory increase does not apply to the iPad Mini, which also went on sale in November.
