Latest Patents

One of Sugita's latest patents is for a microcomputer that features different memory capacities that can be selected. This invention allows for the selection of either of two memory capacity select circuits using a mask that is utilized for selecting data from a mask ROM. The selected output is then used to modify the address space in which a built-in ROM is effective, enabling the switching of external addresses corresponding to the storage capacity of the built-in ROM. This innovation allows for the selection of at least two kinds of storage capacities for built-in memory and the corresponding external address spaces.

Another notable patent is for a memory control apparatus that possesses data retention capabilities. In this invention, a first sense amplifier reads from a first memory cell array at a normal equilibrium point between a read-'0' operation and a read-'1' operation. A second sense amplifier detects data dissipation by reading data at an equilibrium point higher than the normal equilibrium point from a second memory cell array, which is designed for data dissipation detection and shares the same characteristics as the first memory cell array. An interrupt control circuit issues an interrupt request to a CPU to halt its operation, and in response to an instruction from a memory overwrite control circuit, a write/read/erasure control circuit overwrites data stored in the first memory cell array.
