Abstract
Some embodiments of the invention include a memory device having a number of terminals for transferring input data and output data to and from a memory array. The memory device includes an auxiliary circuit for receiving input auxiliary information associated with the input data and for generating output auxiliary information associated with the output data. The input and output auxiliary information include inverting codes, parity codes, temperature information, and time delay information. The input and output auxiliary information are transferred to and from the memory device on the same terminals that the input data and the output data are transferred. Other embodiments are described and claims.
Claims25
A memory device comprising:
- a plurality of data lines for transferring data and auxiliary information, wherein at least one of the data lines is configured for transferring at least one bit of the data at a first time and for transferring at least one bit of the auxiliary information at a second time;
