Abstract
Some rows of memory cells can be configured to store auxiliary data, which provides data protection for user data stored in the other rows of memory cells. The data protection provided by the auxiliary data can include, but not limited to, error correction and/or detection schemes. To further enhance the protection of data stored in the rows of memory cells, the available space in these rows of memory cells can be used to store preliminary auxiliary data, designed to provide data protection for the auxiliary data itself.
Claims20
A method, comprising:
- during a first portion of one or more first predefined burst lengths:
- sending a signal indicative of a first portion of first auxiliary data from one or more memory dice to provide data protection for first user data via a first data link;
- and
- sending a signal indicative of a first portion of preliminary auxiliary data from the one or more memory dice to provide data protection at least for the first portion of the first auxiliary data via a second data link;
- and
- during a second portion of the one or more first predefined burst lengths:
- sending a signal indicative of a second portion of the first auxiliary data from the one or more memory dice to provide data protection for the first user data via the first data link;
- and
- sending a signal indicative of a second portion of the preliminary auxiliary data from the one or more memory dice to provide data protection at least for the second portion of the first auxiliary data via the second data link.
6 more elements
An apparatus, comprising:
- a first number of rows of memory cells of a memory array, a respective row of memory cells of the first number of rows configured to store:
- first user data;
- first auxiliary data corresponding to the first user data;
- and
- a first portion of second auxiliary data corresponding to second user data;
- and
- a second number of rows of memory cells of the memory array, a respective row of memory cells of the second number of rows configured to store:
- the second user data;
- and
- a second portion of the second auxiliary data corresponding to the second user data.
7 more elements
An apparatus, comprising:
- one or more memory dice, the one or more memory dice configured to, during a first portion of one or more predefined burst lengths:
- exchange a signal indicative of first auxiliary data via a first data link, wherein the first auxiliary data is to provide data protection for first user data;
- and
- exchange a signal indicative of a first portion of preliminary auxiliary data via a second data link, wherein the preliminary auxiliary data is to provide data protection at least for the first auxiliary data;
- and
- the one or more memory dice further configured to, during a second portion of the one or more predefined burst lengths:
- exchange a signal indicative of second auxiliary data via the first data link, wherein the second auxiliary data is to provide data protection for the first user data;
- and
- exchange a signal indicative of a second portion of the preliminary auxiliary data from the one or more memory dice via the second data link, wherein the second portion of the preliminary auxiliary data is to provide data protection at least for the second auxiliary data.
