摘要
Systems and apparatuses for memory devices utilizing a continuous self-refresh timer are provided. An example apparatus includes a self-refresh timer configured to generate a signal periodically, wherein a period of the signal is based on a self-refresh refresh time interval, wherein the self-refresh refresh time interval is dependent on temperature information. The apparatus may further include a memory bank comprising at least a first subarray and in communication with a first subarray refresh circuit, which may include a first refresh status counter. The first refresh status counter may be in communication with the self-refresh timer and configured to receive the signal from the self-refresh timer, change a count value of the first refresh status counter in a first direction each time the signal is received, and change the count value of the first refresh status counter in a second direction each time the first subarray is refreshed.
