Latest Patents
Haruo Shoji's latest patents include innovative technologies such as a semiconductor memory device, a sector-address conversion circuit, and an address-conversion method. One of his notable inventions aims to provide a semiconductor memory device that can operate in a desired boot block mode, regardless of the original boot block type. This is achieved by facilitating the rewriting of the memory device. The sector address from an external source is inputted into a sector-address conversion circuit, which converts it into an internal address, allowing access to a memory cell array through an address decoder circuit. By configuring each bank of the memory device as a bottom boot type and converting the sector address, the banks can function as a top boot type.
Another significant patent involves a semiconductor memory device and a method of controlling it. This invention includes a plurality of memory cells corresponding to an address space larger than 2 and smaller than 2, along with an invalid address detecting circuit and an invalid signal outputting circuit. Upon command input, the invalid address detecting circuit invalidates a command if it detects that the supplied address signal indicates an invalid address space. This prevents erroneous write or erase operations, thereby reducing power consumption substantially and improving the reliability of the system unit.
