Abstract
The disclosure provides a memory device including: a connection interface; a memory array associated with a parameter; and a memory control circuit configured at least to: receive operations, each of the operations being a read operation or a write operation, through the connection interface to perform the operations on the memory array; detect, based on performing the operations on the memory array, a read error which is either a binary 0 read error or a binary 1 read error; update the error counter by incrementing an counter value of the error counter in response to the read error being the binary 1 read error and decreasing the counter value in response to the read error being the binary 0 read error; and adjust the parameter in response to the counter value having reached a positive predetermined threshold or a negative predetermined threshold.
