Abstract: Upon receipt of a synchronize cache command, valid host data size in the SRAM write buffer is checked. If the valid data size is greater than a predetermined value, valid host data in the SRAM write buffer is flushed directly into an open MLC block based on a one-pass transfer program. However, if the valid host data size is less than the predetermined value, the host data is not flushed to an open MLC block but is instead flushed into a temporary storage location to satisfy the command specifications for a command to synchronize a cache. The host data is maintained in the SRAM write buffer, which receives additional data until full. Once full, the host data in the SRAM write buffer is transferred to an open MLC block in one-pass. If the host data in the write buffer is lost, it may be recovered from the temporary storage location.

Abstract: Disclosed is a fluid parameter measurement device with an annular gap, including a base, a core column, and a swing block. The base is fixed to the core column and pivot-connected to the swing block. The core column penetrates a through hole in the swing block, sealed at both ends with elastic sealing rings to form an annular gap between a wall of the core column and that of the through hole. The core column contains fluid inlet and outlet channels connecting both ends of the annular gap, directing pressurized liquid through the annular gap. An adjustment assembly on the base alters core column-to-through hole concentricity while maintaining parallelism, enabling flow measurement under varying pressures or at constant pressure with adjustable eccentricity. The design simplifies experimental operations through precise concentricity regulation and eccentricity-based gap state control.
