Patent KR-20200016812-A (KR)
Title: Non-volatile memory switch with host isolation
Inventor: GUO LIPING
IPC: G06F13/16
Filed: 2019-08-07
Abstract: An NVM switch has been designed to allow multiple hosts to simultaneously and independently access a single port NVM device. While an active-active multi-host usage configuration allows a variety of uses of a lower cost single port NVM device, an issue of one of the hosts can delay or block transactions between another host and the NVM device. The NVM switch includes a logic that isolates activity of the multiple hosts even when switch logic is shared across the hosts. When the switch detects an issue of one host (error host), the switch clears the in-flight commands of the error host and flushes data of the error host. Likewise, the NVM switch ensures proper communication of error reporting from connected NVM devices to the multiple hosts.
