Abstract
An advanced input/output interface is provided for an integrated circuit memory having a memory storage array accessible by signals formatted in a two-level protocol. The advanced input/output interface includes a bit compression circuit for receiving a first plurality of signals formatted in the two-level protocol and generated within the integrated circuit memory. The bit compression circuit converts the first plurality of two-level protocol signals into a first signal formatted in a multi-level protocol. A bit decompression circuit receives a second signal formatted in the multi-level protocol. The bit decompression circuit converts the second multi-level protocol signal into a second plurality of signals formatted in the two-level protocol. In one embodiment, the advanced input/output interface allows for high speed/bandwidth memory accesses while reducing the pin count and operating frequency required for operation.
