Abstract

Techniques are disclosed relating to data inversion encoding. In one embodiment, an apparatus includes an interface circuit. The interface circuit is configured to perform first and second data bursts that include respective pluralities of data transmissions encoded using an inversion coding scheme. In such an embodiment, the initial data transmission of the second data burst is encoded using the final data transmission of the first data burst. In some embodiments, the first and second data bursts correspond to successive write operations or successive read operations to a memory module from a memory PHY.
