Apparatuses, systems, methods, and computer program products are disclosed for accessing non-volatile memory. An apparatus includes one or more memory die. A memory die includes an array of non-volatile memory cells, a set of ports, and an on-die controller. The set of ports includes a first port and a second port. The first port includes a first plurality of electrical contacts and the second port includes a second plurality of electrical contacts. The on-die controller communicates via the set of ports to receive command and address information and to transfer data for a data operation on the array of non-volatile memory cells. The on-die controller uses the first port and the second port in a first mode and uses the first port without the second port in a second mode. The second mode provides compatibility with an interface of a legacy type of memory die. 公开了用于访问非易失性存储器的装置、系统、方法和计算机程序产品。种装置包括个或多个存储器裸片。存储器裸片包括非易失性存储器单元阵列、组端口、以及裸片上控制器。所述组端口包括第端口和第二端口。所述第端口包括第多个电触头，并且所述第二端口包括第二多个电触头。所述裸片上控制器经由所述组端口进行通信以接收命令和地
