ROM - Read Only Memory. An erasable programmable read-only memory (EPROM) using the Hall effect to detect the direction of magnetic moment of a ferromagnetic storage element has been proposed by Timoshkov et al., as shown in Fig. For writing and erasing data on the EPROM, we need a particular device which is known as PROM programmer. EPROM (Erasable and Programmable Read Only Memory… permanenter Halbleiterspeicher, in dem Daten dauerhaft und unveränderlich gespeichert werden. Out of these two arrays AND plane is fixed and OR plane is programmable. The most promising leakage reduction techniques that have been proposed are introduced, analyzed and compared into 65 nm low-power PD-SOI technology, taking into account all the SOI specific effect. High voltage transistors in combination with deep polysilicon filled trench isolation results in, parasitic devices.In figure 10 a parasitic NMOS is shown in series with a parasitic PMOS tran-, sistor. based on a vertical MOS transistor in a trench, and a doubling of the rules is presented. Both NMOS and PMOS have n- epi around, their source and drain to gain a high breakdown. für erasable programmable read-only memory, wörtlich löschbarer programmierbarer Nur-Lese-Speicher) ist ein nichtflüchtiger elektronischer Speicherbaustein, der bis etwa Mitte der 1990er-Jahre vor allem in der Computertechnik eingesetzt wurde, inzwischen aber weitgehend durch EEPROMs abgelöst ist. time programmable, read-only memory (OTP EPROM) organized as 32K by 8 bits. Read-only memory (ROM) is similar in design to static or dynamic RAM circuits, except that the “latching” mechanism is made for one-time (or limited) operation. … By using gradated patterns as learning and unknown patterns, it is shown that recalling accuracy become higher than using original pattern themselves. The conclusions of the paper show that letting the bit lines float during the idle mode is mandatory to diminish the cell leakage current and help to protect the cell content against the bit-line aggressions. 11). No autodope is, Fig 6) Reverse diode characteristics of a 0.1 mm, poly diode. On a neural network of perceptron type with feedback, error back-propagation algorithm, The paper presents a detailed study on the idle leakage reduction techniques on partially depleted silicon-on-insulator (PD-SOI) CMOS SRAM. Once data has been written onto a ROM chip, it cannot be removed and can only be read. System considerations Switching between active and standby conditions via the chip enable pin may produce transient voltage excursions. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile.It is an array of floating-gate transistors … the other end of the terminal, the dimension should not. It can be programmed only once and is not erasable. Obviously, once one of the little fuses is blown, it cannot be … The magnetic film of high coercivity and perpendicular anisotropy is used for data storage, and the Hall element for data reading. A novel mask-ROM technology enabling a twofold packing density The on-off ratio and breakdown voltage is sufficient for application, in a large memory matrix even at elevated temperatures (Fig. features of the ROS-technology are demonstrated by means of a 1 Mbit be measured in that radius area. Also parasitic devices, formed due to the usage of trench poly, and there, the process flow was presented. Sie sind auf der linken Seite unten aufgeführt.
