Abstract: A mapping table H2F update technique for a FLASH memory is disclosed. In a disclosed data storage device, the controller updates a logical-to-physical address mapping table between a host and the FLASH memory in accordance with a group count of a buffer block of the FLASH memory. The group count reflects a logical address distribution of write data buffered in the buffer block and with non-updated logical-to-physical address mapping information. The higher the group count, the more dispersed the logical address distribution. In this manner, each update of the logical-to-physical address mapping table just takes a short time.

Abstract: Detecting heap spraying on a computer by detecting a plurality of requests to allocate portions of heap memory, measuring the plurality of requests to determine a value of a characteristic of the plurality of requests, identifying an activity consistent with heap spraying by determining that the value of the characteristic is consistent with a benchmark value of the characteristic, wherein the benchmark value of the characteristic is associated with heap spraying, and performing a computer-security-related remediation action responsive to determining that the value of the characteristic is consistent with the benchmark value of the characteristic.

Abstract: Methods and apparatus are disclosed for generating a result based on a lookup result from a lookup operation using an associative memory and processing based on a discriminator portion of a lookup word. A first lookup operation is performed to generate a lookup result. In one implementation, a second lookup operation is performed based on a discriminator or the lookup result depending on the result of an evaluation, such as whether there was a hit or the lookup result matches a predetermined value. In one implementation, a second lookup operation is performed based on the discriminator, and either the result of the first or second lookup operation is used for subsequent processing. One implementation performs a lookup operation based on a lookup word to generate a lookup result, which is used to retrieve a base address and a bitmap from a memory.

Abstract: An apparatus, system, and method are disclosed for an alternate lock facility connection path. A request module receives a connection request to establish redundant connection paths between a control unit and a host. A primary connection module establishes a first connection path between the control unit and the host through a first communication channel. An alternate connection module establishes a second connection path between the control unit and the host through a second communication channel. A detection module detects a failure of the first connection path. A redirection module redirects communication between the control unit and the host through the second connection path upon detection of a failure of the first connection path.
