Abstract

Systems, apparatuses, and methods for organizing bits in a memory device are described. In a number of embodiments, an apparatus can include an array of memory cells, a data interface, a multiplexer coupled between the array of memory cells and the data interface, and a controller coupled to the array of memory cells, the controller configured to cause the apparatus to latch bits associated with a row of memory cells in the array in a number of sense amplifiers in a prefetch operation and send the bits from the sense amplifiers, through a multiplexer, to a data interface, which may include or be referred to as DQs. The bits may be sent to the DQs in a particular order that may correspond to a particular matrix configuration and may thus facilitate or reduce the complexity of arithmetic operations performed on the data.

First claim

What is claimed is:

1. An apparatus, comprising:
an array of memory cells;
a data interface;
a column decode circuitry coupled between the array of memory cells and the data interface; and
a controller coupled to the array of memory cells, the controller configured to cause the apparatus to:
perform a number of prefetch operations, wherein each of the number prefetch operations reads a particular amount of data from the array of memory cells to a number of sense amplifiers; and
select a first portion of the particular amount of data to correspond to a matrix configuration by selecting a first number of bits of the particular amount of data, via a single multiplexer coupled to each of the number of sense amplifiers and to the data interface, to transfer from the number to sense amplifiers to the data interface.

2. The apparatus of claim 1 , wherein the first number of bits correspond to a first row of the matrix configuration.

3. The apparatus of claim 1 , wherein the column decode circuitry is configured to send the first number of bits to the data interface.

4. The apparatus of claim 1 , wherein the controller is further configured to cause the column code circuitry to select the first number of bits.

5. The apparatus of claim 1 , wherein the prefetch operation stores the particular amount of data in the number of sense amplifiers.

6. The apparatus of claim 1 , wherein the controller configured to cause the apparatus to select a second number of bits from the particular amount of data that to correspond to the matrix configuration.

7. The apparatus of claim 6 , wherein the second number of bits corresponds to a second row of the matrix configuration.

8. The apparatus of claim 6 , wherein the column decode circuitry is configured to send the second number of bits to the data interface.

9. A method, comprising:
performing a number of prefetch operations, wherein each of the number prefetch operations reads a particular amount of data from an array of memory cells to a number of sense amplifiers; and
selecting a first portion of the particular amount of data to correspond to a matrix configuration by selecting a first number of bits of the particular amount of data, via a single multiplexer coupled to each of the number of sense amplifiers and to a data interface, to transfer from the number to sense amplifiers to the data interface.

10. The method of claim 9 , wherein selecting the first number of bits of the particular amount of data correspond to a first row of the matrix configuration.

11. The method of claim 9 , wherein selecting the first number of bits of the particular amount of data correspond to a first column of the matrix configuration.

12. The method of claim 9 , further including selecting a second portion of the particular amount of data to correspond to the matrix configuration by selecting a second number of bits of the particular amount of data to transfer from the number to sense amplifiers to the data interface.

13. The method of claim 12 , wherein selecting the second number of bits of the particular amount of data corresponds to a second row of the matrix configuration.

14. The method of claim 12 , wherein selecting the second number of bits of the particular amount of data corresponds to a second column of the matrix configuration.

15. A method, comprising:
performing a number of prefetch operations, wherein each of the number prefetch operations reads a particular amount of data from the array of memory cells and stores the particular amount of data in a number of sense amplifiers; and
selecting a first number of bits of the particular amount of data that correspond to a matrix configuration, via a single multiplexer coupled to each of the number of sense amplifiers and to a data interface, to transfer from the number to sense amplifiers to the data interface.

16. The method of claim 15 , wherein selecting the first number of bits includes selecting data stored in consecutive sense amplifiers.

17. The method of claim 16 , wherein the first number of bits corresponds to a first row of the matrix configuration.

18. The method of claim 15 , wherein selecting the first number of bits includes selecting data stored in every eighth sense amplifier starting with a first sense amplifier.

19. The method of claim 18 , wherein the first number of bits corresponds to a first column of the matrix configuration.

20. The method of claim 15 , further including selecting a second number of bits of the particular amount of data the correspond to the matrix configuration to transfer from the number to sense amplifiers to the data interface.
