Abstract
Examples include techniques for a write zero operation. Example techniques include forwarding a write 0 command to a memory device to cause internal activations of column select lines of one or more blocks of memory to cause bit values or contents of the one or more blocks to have or store a value of 0.
Claims25
An apparatus comprising:
- a controller for a memory device that includes logic, at least a portion of which comprises hardware, the logic to:
- forward a write 0 command to cause all bit values in a block of memory of the memory device to have a value of 0;
- cause all global input/output (GIOs) to the block of memory to have a GIO value of 0;
- and
- cause an internal activation of all column select lines (CSLs) to the block of memory by the memory device, the internal activation of all CSLs to cause the GIO value of 0 to be written to a first portion of the block of memory before a write line is internally activated by the memory device.
2 more elements
A method comprising:
- forwarding, at a controller for a memory device, a write 0 command to cause all bit values in a block of memory of the memory device to have a value of 0;
- causing all global input/output (GIOs) to the block of memory to have a GIO value of 0;
- and
- causing an internal activation of all column select lines (CSLs) to the block of memory by the memory device, the internal activation of all CSLs to cause the GIO value of 0 to be written to a first portion of the block of memory before a write line is internally activated by the memory device.

An apparatus comprising:
- a controller for a memory device that includes logic, at least a portion of which comprises hardware, the logic to:
- forward a write 0 command to cause one or more blocks of memory for the memory device to store a value of 0;
- and
- cause internal activation of column select lines (CSLs) to the one or more blocks of memory by the memory device, the internal activation of the CSLs to occur in a sequential manner until all columns of the one or more blocks of memory have been activated and the one or more blocks of memory store the value of 0.
