Abstract
A method for initializing a control device of a memory, the control device executing commands for accessing the memory transmitted to the memory by a control signal, the method comprising steps of detecting the switching on of the memory and of at least partially initializing the control device following the switching on of the memory. According to one embodiment of the present invention, the method comprises steps of detecting a specific event in the control signal, and of at least partially initializing the control device following the detection of the specific event.
Claims18
A method comprising:
- detecting a switching on of a memory having a memory array and a control device that accesses the memory array in response to read commands transmitted to the memory by a control signal;
- at least partially initializing the control device by issuing a first initialization signal in response to detecting the switching on of the memory;
- detecting a specific event in the control signal;
- and
- at least partially initializing the control device by issuing a second initialization signal in response to detecting the specific event, wherein the specific event is a write command for writing in the memory and is not associated with a write address.
A memory comprising:
- a memory array;
- and
- a control device operable to execute read commands for reading the memory, the control device including:
- a control signal input configured to receive the read commands via a control signal;
- a detector circuit configured to detect a switching on of the memory and at least partially initialize the control device in response to the switching on of the memory;
- and
- an initialization circuit configured to detect a specific event in the control signal and at least partially initialize the control device in response to detecting the specific event, wherein the specific event is a write command for writing in the memory array and is not associated with a write address.
A memory system comprising:
- a memory device;
- control means for executing commands to access the memory device, the commands being transmitted via a control signal applied to the memory device;
- detector means for detecting an enabling of the memory device and at least partially initializing the control means following the enabling of the memory device;
- and
- initialization means for detecting an event within the control signal and at least partially initializing the control means upon detecting the event, wherein the event is a command for writing or reading in the memory device and is not associated with a write or read address.
A method comprising:
- detecting a switching on of a memory having a memory array and a control device that accesses the memory array in response to read commands transmitted to the memory by a control signal;
- at least partially initializing the control device by issuing a first initialization signal in response to detecting the switching on of the memory;
- detecting a specific event in the control signal;
- and
- at least partially initializing the control device by issuing a second initialization signal in response to detecting the specific event, wherein the specific event is a read command for reading from the memory and is not associated with a read address.
