Recently, a non-volatile memory with high density and low delay, called Racetrack Memory (RM), has attracted much attention.
In RM, data is disturbed by shift operations resulting position errors, i.e. insertion/deletion errors.
For a high speed reading in RM,
reading of data with multiple read heads has been investigated.
In this paper,
we define a channel model of insertion/deletion errors with multiple read heads.
Moreover, we propose a decoding algorithm of low-density parity-check (LDPC) codes for such channel.
We show by simulations that bit error rate (BER) comparison in terms of different numbers of read heads and data size,
and we show effectiveness of the proposed decoding algorithm. |
