controller core accepts commands using a simple local interface and translates them to the command sequences required by LPDDR4 devices. The core also performs all initialization, refresh and power-down functions.<\/p><p>The core uses bank management modules to monitor the status of each LPDDR bank. Banks are only opened or closed when necessary, minimizing access delays.<\/p><p>The core queues up multiple commands in the command queue. This enables optimal bandwidth utilization for both short transfers to highly random address locations as well as longer transfers to contiguous address space. The command queue is also used to opportunistically perform look-ahead activates, precharges and auto-precharges further improving overall throughput.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-67d41a58 elementor-widget elementor-widget-image\" data-id=\"67d41a58\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"720\" height=\"400\" src=\"https:\/\/www.rambus.com\/wp-content\/uploads\/2019\/12\/LPDDR4-Controller-Core.png\" class=\"attachment-large size-large wp-image-23926\" alt=\"LPDDR4 Controller Core Block Diagram\" srcset=\"https:\/\/www.rambus.com\/wp-content\/uploads\/2019\/12\/LPDDR4-Controller-Core.png 720w, https:\/\/www.rambus.com\/wp-content\/uploads\/2019\/12\/LPDDR4-Controller-Core-150x83.png 150w, https:\/\/www.rambus.com\/wp-content\/uploads\/2019\/12\/LPDDR4-Controller-Core-300x167.png 300w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">LPDDR4X\/4 Controller Core Block Diagram<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6752a8d2 elementor-widget elementor-widget-text-editor\" data-id=\"6752a8d2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The core is provided with run-time programmable inputs for all memory timing parameters and configuration settings.
