Channel Estimation for Multi-Level Memories Using Pilot signals
(2010)
Abstract
Embodiments of the present invention provide channel estimation for multi-level memories using pilot signals. A memory apparatus includes a memory block comprising a plurality of memory cells and adapted to operate with at least two levels of signals for writing data into and reading data from the memory cells. At least two memory cells are employed as reference cells to output a plurality of pilot signals. The memory apparatus also includes a channel block operatively coupled to the memory block, and adapted to facilitate the writing and reading of data into and from the memory cells. The channel block is also adapted to receive the pilot signals and determine one or more disturbance parameters based at least in part on the pilot signals and to compensate the read back signals based at least in part on the determined one or more disturbance parameters during said reading of data from the memory cells. Other embodiments may be described and claimed.
