Patent number: 11029859Abstract: A memory system includes a memory controller having a bank command scheduler implemented in a hardware logic block and a power budget controller including a power budget register and a credit register. The hardware logic block is able to determine a command in a queue to be transmitted to a memory bank over a channel, estimate a power consumption value for the command, and query the power budget controller to determine if the power consumption value is within a threshold. If the power consumption value is within the threshold, the hardware logic block receives a grant response from the power budget controller, adds the power consumption value to the credit register value, transmits the command over the channel, and transmits a signal to the power budget controller indicating that the command has been executed and that the power consumption value should be subtracted from the credit register value.Type: GrantFiled: August 23, 2017Date of Patent: June 8, 2021Assignee: Toshiba Memory CorporationInventors: Julien Margetts, Hyoun Kwon Jeong, Jonghyeon Kim
