A recently granted patent (Publication Number: US11887688B2) discloses a method for efficiently managing memory cells in a memory device. The method involves receiving activation commands to open rows of memory cells in different subarrays of a memory bank. By activating a portion of a subarray based on an indication received before the actual activation command, the method optimizes the process of accessing memory cells. Additionally, the method includes generating timing signals based on the received commands to ensure the timely activation and deactivation of memory cells, ultimately improving the overall performance of the memory device.

Furthermore, the patent also covers an apparatus that implements the method described. The apparatus includes a bank of memory cells with multiple subarrays and a controller responsible for executing the steps outlined in the method. By receiving and processing activation commands and indications in a specific sequence, the apparatus can efficiently manage memory access operations, leading to enhanced speed and performance. This innovative approach to memory cell management showcases advancements in memory technology, particularly in optimizing memory access operations for improved efficiency and speed in memory devices.
