Embodiment Construction

[0020] The present invention will now be described by means of embodiments. It should be noted that the embodiments should be understood as illustrative only, not limiting the present invention.

[0021] figure 1 The encoder Cod11 is shown, which converts the k-bit binary data sequence u=u 1 ,...,u k (where, k≥2) encoded as n-bit encoded binary data sequence x=x 1 ,...,x n , where n>k corresponds to a linear code C.

[0022] A linear code C can be described as usual by a (k,n) generator matrix G with k rows and n columns, and an (n−k,n) parity check matrix H, also called the H matrix. The encoded binary data sequence x is determined from the binary data sequence u by

[0023] x=(x 1 ,...,x n ) = (u 1 ,...,u k )·G=u·G (1)

[0024] k-bit data sequence u=u 1 ,...,u k Available on the k-bit input line 12 of the encoder Cod11, and the data sequence x=x determined according to formula (1) 1 ,...,x n Output on n-bit output line 13.

Abstract

The invention relates to a device and a method for correction of ternary stored binary data, in which the binary data is transformed to and stored as ternary data. The storage device uses memory cells capable of storing three states. The device and method furthermore are configured to identify and correct falsified ternary data when reading and outputting the data from storage device.

Description

technical field [0001] The present invention relates to a device and a method for storing data, in particular for storing binary data in a memory using ternary storage. A method and a corresponding circuit are provided which allow correction of stored binary data. Background technique [0002] Today's data processing systems operate on data represented by any processing device in a binary format. The storage of these data takes place in memory devices, typically using a binary storage system comprising memory cells. Typically, each memory cell stores one bit, that is, the memory cell can store two distinguishable states, representing the state of the bit, ie, 1 or 0. The binary data stream to be stored may be passed to a storage device for storage. The storage device is adapted and configured to correspond to the storage unit of the incoming data stream when receiving data for storage, and to read data from the storage unit upon request. [0003] However, the data read f...
