Abstract
A memory chip includes at least two memory blocks. In a method for controlling power supply for the memory blocks of the memory chip, each memory block receives a command for switching to standby mode. The commands are issued, for example by a processor, separately for each memory block in order to be able to individually place the memory block in standby mode.
Claims12
A power supply control method for a memory chip including at least two memory blocks, comprising:
- storing a standby mode command for each memory block in a non-volatile memory that is separate from the at least two memory blocks;
- and
- in response to an assertion of a reset signal:
- passing of the standby mode command for each memory block from the non-volatile memory to each memory block;
- configuring a standby mode state of each memory block after reset to correspond to the passed standby mode command.
