Abstract
Apparatuses and methods for charging a global access line prior to accessing a memory are described. An example apparatus may include a memory array of a memory. A plurality of global access lines may be associated with the memory array. The global access line may be charged to a ready-access voltage before any access command has been received by the memory. The global access line may be maintained at the ready-access voltage during memory access operations until the receipt of a post-access command. The post-access command may reset the global access line to an inactive voltage.
Claims20
An apparatus comprising:
- a memory array including signal lines;
- and
- voltage circuitry configured to charge at least one signal line of the memory array to a ready-access voltage based on a temperature control signal, the temperature control signal responsive to a pre-access command.
A method comprising:
- responsive to a pre-access command:
- receiving a control signal including a temperature of a memory, the signal including information to prepare a signal line of a memory for memory access based on the temperature of the memory;
- and
- charging, by a voltage generator, a voltage for the signal line based partly on a temperature of the memory;
- and
- accessing the memory.
