Example memory systems, methods, and media for aggregating responses from memory systems to mitigate interrupt overhead in hosts coupled to the memory systems are disclosed. One example method includes receiving multiple commands from a host. Multiple responses are sent to the host at a time instant, where each of the responses is generated in a memory system during a time period and responsive to a respective one of the commands.

Response control in memory systems for reducing interrupt overhead

In an aspect, a method for managing a logic to physical (L2P) mapping table of a memory device is disclosed. A first configuration corresponding to a file is received from a host device with the memory device. Transmitting an L2P dirty entry notification associated with the file to the host device is refrained from. The L2P dirty entry notification indicates that an L2P entry of an L2P mapping table stored in the host device has become dirty. In response to the refraining, a first confirmation is transmitted to the host device.

File system and host performance booster for flash memory

Disclosed herein are system, method, and computer program product aspects for managing a storage system. In an aspect, a host device may generate a configuration corresponding to a file and transmit the configuration to a memory device, such as 3D NAND memory. The configuration instructs the memory device to refrain from transmitting a logic-to-physical (L2P) dirty entry notification to the host device. The L2P dirty entry notification corresponds to the file. The host device may also generate a second configuration corresponding to the file and transmit the second configuration to the memory device. The second configuration instructs the memory device to resume transmitting the L2P dirty entry notification corresponding to the file to the host device.

The disclosure uses the Carter's coefficient to correct the equivalent electromagnetic air gap length. And the specific permeance on both sides of the primary core is obtained. Then, the permeance on both sides based on the structure of the primary core is calculated. An equation is established by using the continuity principle of flux, thereby obtaining the air gap magnetomotive force model of current-carrying conductor. The slot vector diagram of magnetomotive force in short primary linear machine is illustrated according to that in the rotating machine. Then, based on the winding arrangement and vector combination, the amplitude and phase of various spatial harmonic wave of the three-phase winding are obtained. Finally, the characteristics of average component distribution of the current-carrying conductor are adopted to obtain the pulsating magnetomotive force generated by the three-phase winding of the linear machine.
