A storage device includes a cell degradation measurement circuit configured to receive a cell degradation information request command that requests cell degradation information from a host, and provide first cell degradation information to the host in response to the cell degradation information request command, and a non-volatile memory including a plurality of memory cells. The cell degradation measurement circuit writes data to any one of the plurality of memory cells in response to the cell degradation information request command. The cell degradation measurement circuit reads the written data after a predetermined time has elapsed. The first cell degradation information is generated based on an error detection operation performed on the read data.

A memory controller may calculate a sum of a first number of entries stored in a read buffer and a second number of entries stored in a write buffer. If the sum is less than a first threshold and the read/write buffer is not full of entries, then the memory controller can request read/write commands from a host computing device. If the sum is not less than the first threshold or the read/write buffer is full of entries, then the memory controller can assert backpressure to stop the incoming flow newly incoming read/write commands from the host computing device. Additionally, or alternatively, the memory controller may dequeue a write command entry only if a number of write command entries stored in a write command FIFO memory is greater than a second threshold. The memory controller may dequeue read command stored in a read FIFO memory if the number of write command entries stored in the write command FIFO memory is less than or equal to the second threshold and the read FIFO memory is not empty of the read command entries.

Provided is a system and method for storing, via a processor, in a memory of an application specific integrated circuit (ASIC), one or more threshold values responsive to at least one of physical layer and processing layer operating conditions of the ASIC. Also included is monitoring at least one of a physical layer operating condition value and a processing layer performance condition value of the ASIC, the moderating forming a monitored value, comparing the monitored value with the stored threshold values, and throttling processing layer performance of the ASIC when the monitored value exceeds at least one of the stored threshold values.
