APPARATUSES AND METHODS FOR DATA TRANSFER FROM SENSING CIRCUITRY TO A CONTROLLER
First Claim
1. An apparatus, comprising:
- a controller coupled to a memory device, the controller configured to;
execute a command to transfer data from a latch component to a register file in the controller, wherein the memory device comprises;
an array of memory cells;
the latch component coupled to rows of the array via a plurality of columns of the memory cells, the latch component including a latch selectably coupled to each of the columns and configured to implement the command to transfer the data; and
a data line to couple the latch component to the register file to transfer the data; and
wherein the controller is configured to couple to the data line and the register file to perform a write operation on the transferred data to the register file in the controller.

Abstract
The present disclosure describes data transfer in a memory device from sensing circuitry to controller. An example apparatus includes a controller coupled to a memory device. The controller is configured to execute a command to transfer data from a latch component to a register file in the controller. The memory device includes an array of memory cells and the latch component is coupled to rows of the array via a plurality of columns of the memory cells. The latch component includes a latch selectably coupled to each of the columns and configured to implement the command to transfer the data. The memory device includes a data line to couple the latch component to the register file to transfer the data. The controller is configured to couple to the data line and the register file to perform a write operation on the transferred data to the register file in the controller.
