Abstract
The present disclosure relates to a memory circuit having a shared control device for access to target and complementary memory devices for improved differential sensing. The memory circuit has a control device arranged within a substrate and having a first terminal coupled to a source-line, a second terminal coupled to a word-line, and a third terminal. A first memory device has a first lower electrode separated from a first upper electrode by a first data storage layer. The first upper electrode is coupled to the third terminal and the first lower electrode is coupled to a first bit-line. A second memory device has a second lower electrode separated from a second upper electrode by a second data storage layer. The second upper electrode is coupled to the second bit-line and the second lower electrode is coupled to the third terminal.
