A semiconductor device includes a sampling code generation circuit and a code comparator. The sampling code generation circuit includes a buffer circuit configured to receive an external set signal. The sampling code generation circuit is configured to perform a count operation during a sampling period, the sampling period adjusted based on an output signal of the buffer circuit to generate a sampling code. The code comparator is configured to compare the sampling code with a reference code to generate a comparison flag.

Embodiments of the present disclosure provide a system for testing multicore firmware (FW) in a memory system and a method thereof. A test system includes a test device and a storage device including a plurality of flash translation layer (FTL) cores, each FTL core associated with multiple memory blocks. The test device generates test preconditions for the plurality of FTL cores and provides the test preconditions to the plurality of FTL cores, the test preconditions being different from each other. Each of the plurality of FTL cores performs one or more test operations based on a corresponding test precondition of the test preconditions.

Technologies for performing a quick reliability scan include, for a particular block of a set of blocks of different block types. Each block of the set of blocks includes pages of memory of a physical memory device. A subset of the pages of the block is identified. The block is scanned by scanning the subset of the plurality of pages of the block for a fold condition. A page of the subset of the plurality of pages is determined to have the fold condition. After the set of blocks has been scanned, the folding of the block that includes the page that has been determined to have the fold condition is requested.

Exemplary methods, apparatuses, and systems include receiving a plurality of read operations. The read operations are divided into a current set of a sequence of read operations and one or more other sets. The size of the current set is a first number of read operations. An aggressor read operation is selected from the current set. A data integrity scan is performed on a victim of the aggressor and a first indicator of data integrity is determined based on the first data integrity scan. A size of a subsequent set of read operations is set to a second number, which less than the first number, based on the indicator of data integrity.

The present disclosure provides a semiconductor test method. The semiconductor test method includes the operations of: receiving a source code written in an interpreted language; and performing, by a first test apparatus, a first test on a device under test (DUT) based on the source code. The operation of performing, by the first test apparatus, the first test on the DUT based on the source code includes the operations of: interpreting, by a processor, the source code to generate a first interpreted code; and performing the first test on the DUT according to the first interpreted code. The first test apparatus is configured to execute the first interpreted code written in a first language.
