Storage channel architectures for advanced memory and information storage systems

Signal Processing&Channel Coding for Advanced Data Storage

• Digital universe gap, storage available (information creation)
• Need significant research efforts on advanced storage technologies
• Signal processing and coding become critical to recover data reliably from such challenging channels

Channel Signal Processing for Non-Volatile Memories

Coding and signal processing for mitigating the effects of degradations such as ICI and low cycling endurance, etc.

• Coding with side information at the encoder (CSIE) and decoder (SCID)
• Iterative cross-entropy encoding
• Statistical signal processing for suppressing inter- cell interference (ICI)

Multi-track and multi-wordline joint signal processing for advanced information storage channels

Read Channel for Advanced Data Storage Systems

Intensive signal processing and coding for ultra-high density data storage system

• Advanced channel modeling with granular or semi-granular recording media
• Research on multi-reader joint equalizer and Quasi-2D detector for array-reader

ITI cancellation for Advanced Data Storage Systems

Mitigating inter-track interference (ITI) for the squeezed track in IMR is not straightforward due to the non-negligible frequency offset between neighboring tracks
