Memory power coordination
The present disclosure includes apparatuses and methods related to bank coordination in a memory device. A number of embodiments include a method comprising concurrently performing a memory operation by a threshold number of memory regions, and executing a command to cause a budget area to perform a power budget operation associated with the memory operation.
Digital signal processing device and control method of digital signal processing device
A digital signal processing device includes a control unit that performs control to alternately burst transfer burst length audio data in a first half area of a first buffer memory and burst length audio data in a second half area of the first buffer memory to a DRAM, in which the control unit performs control to burst transfer the burst length audio data in the first half area of the first buffer memory to the DRAM while writing audio data one word at a time to the second half area of the first buffer memory in sequence and performs control to burst transfer the burst length audio data in the second half area of the first buffer memory to the DRAM while writing audio data one word at a time to the first half area of the first buffer memory in sequence.

Combined ECC and transparent memory test for memory fault detection
Embodiments combine error correction code (ECC) and transparent memory built-in self-test (TMBIST) for memory fault detection and correction. An ECC encoder receives input data and provides ECC data for data words stored in memory. Input XOR circuits receive the input data and output XOR'ed data as payload data for the data words. Output XOR circuits receive the payload data and output XOR'ed data. An ECC decoder receives the ECC data and the XOR'ed output data and generates error messages. Either test data from a controller running a TMBIST process or application data from a processor executing an application is selected as the input data. Either test address/control signals from the controller or application address/control signals from the processor are selected for memory access. During active operation of the application, memory access is provided to the processor and the controller, and the memory is tested during the active operation.

MEMORY SYSTEM, CONTROL METHOD, AND POWER CONTROL CIRCUIT
A memory system includes: a first nonvolatile memory; a second volatile memory; a controller; a power control circuit configured to perform control such that a first voltage is applied to the first memory, the second memory, and the controller based on first power supplied from an external power supply; and a power storage device configured to supply second power to the power control circuit while the first power from the external power supply is interrupted. While the first power supplied from outside is interrupted, the power control circuit applies a second voltage based on the second power supplied from the power storage device to the first memory, the second memory, and the controller. The power control circuit stops the application of the second voltage to the second memory after the data is read from the second memory and before the data is written into the first memory.
