Samsung patents memory chip design that buffers commands to keep data flowing
Samsung has been granted a patent for a memory device that uses a specific circuit to manage instructions sent to the chip. The system includes a queue that temporarily holds certain commands and a monitor that checks the status of the data line before releasing them, ensuring the memory receives instructions at the right time.
In the filing’s own words
Provided is a memory device including a control logic circuit connected to a first bus and configured to receive a first command-address and a second command-address from an external device, an input/output (I/O) circuit connected to a second bus and configured to transmit and receive data to and from the external device, and a command-address management circuit configured to store the second command-address from the control logic circuit.
What exactly they claim (claim 1)
1. A memory device comprising: a memory cell array including a first memory plane and a second memory plane; a control logic circuit connected to a first bus, the control logic circuit configured to receive a first command-address and a second command-address from an external device; an input/output (I/O) circuit connected to a second bus, the I/O circuit configured to transmit and receive data to and from the external device; and a command-address management circuit configured to receive the second command-address from the control logic circuit based on a state of the second bus, wherein the command-address management circuit includes, a command-address queue configured to store the second command-address, and a monitoring circuit configured to monitor the state of the second bus.
