Description of the Invention (1) Fu Xianquan of the Invention This case claims a co-pending U.S. provisional application filed on March 4, 1999 No. 6 0/1 22, 73 No. 1 priority. Related Patent Applications The following provisional applications are related to the present invention: Provisional Application No. 60 / 122,73 3 Provisional Application No. 60/1 2 1,9 0 1 Provisional Application No. 6 0/1 2 1,925 Provisional Application No. 60/1 2 Provisional Application No. 2,822. FIELD OF THE INVENTION The present invention relates to non-electric random access memory. More specifically, the present invention relates to a magnetoresistive sensor with a single collector for non-electric random access ferromagnetic memory. BACKGROUND OF THE INVENTION Computer memory technology has undergone far-reaching advancements in the first two decades. A first-generation computer memory involves magnetic core memory technology. To form each core, a small ring-shaped ferrite core is interwoven into a matrix of fine wires. By applying an electric current through these wires, the core is programmed into Point to the flux path north or south at logic 1 or 0. The advantage of magnetic memory is that it is non-electrical, or does not need to be updated to memorize the stored logic signals. In addition, the magnetic memory is also '" radiation non-inductive radon, or free from ionizing radiation such as radon rays 〇 However, the assembly of the magnetic core array is extremely labor-intensive and was abandoned immediately when the semiconductor method was developed. Currently, one of the most common memory technologies uses M0S (Metal Oxide Paper Standard Applies to Chinese National Standards (CNS) A4 Specifications (210 X 297 Gong Chu) '----- II 1 · I 1 (I -------- Order · ---- JI 1 {Please read the note on the back first k Lettuce Page) 46316 A7 B7 Printed by employees of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the cooperative V. Invention Description (2) Conductor) or CMOS (Complementary Metal Oxide Semiconductor) Method 0 However, it is generally known 'due to the inherent leakage of capacitors, this technique Each memory cell needs to be constantly updated to maintain the logic signal strength. This memory cell constant update is not a problem when the voltage source is not limited, but in many applications such as stacked computers and cellular phones, the power supply is limited. To address this problem, rechargeable batteries have been used in all portable electrical devices. A problem associated with using devices with capacitive memory arrays is the inconvenience of maintaining each battery properly charged every hour. Therefore, there is a need for a non-dependent memory device that is inexpensive and fast to make without updating. Examples of patents related to non-dependent random access memory are as follows, each of which is supported by its supportive indication Incorporated herein by reference: U.S. Patent No. 4,360,899 issued to Dimyan et al. Shows a non-electrical random access memory having a plurality of magnetic cells arranged in an array on a major surface or substrate. A single magnetic field is selected during operation. And simultaneously apply an electrical pulse to a pair of conductors that intersect adjacent to the selected grid and inductively switch between the opposite residual (ie, permanent) states. Each electrical pulse has an amplitude that is not sufficient to inductively convert the residual state of the selected grid. However, the combined amplitude of each electrical pulse is at least equal to the amplitude required for this conversion. U.S. Patent No. 08,826, issued to Matehews, shows a non-electrostatic static magnetic memory device based on the Hall effect operation. The device includes a magnetic patch for storing data in the form of a magnetic field, a semiconductor Hall bar, and a pair of body-shaped bipolar transistors used to amplify and buffer the Hall voltage generated along the Hall bar. When used, the current is Forced to flow down the length of the Hall stick, resulting in a Hall voltage across the direction of both the magnetic field and the current.

Description of the invention (3) Production: The base of the bipolar transistor is ohmically coupled to the Hall rod to sense the Hall voltage and its polarity represents the stored information. Finally, A current carrying conductor system is used to write data to individual magnetic patches. U.S. Patent No. 5,295,097 issued to Lienau shows a non-electrical random access memory having a plurality of independent magnetic polarization domains. Each domain is surrounded by a full-write loop component and is configured to penetrate the Hall channel of a double-drain field-effect transistor (FET) with its residual magnetic field. The domains are grouped by words and links, and each is written by a single full write current through the enclosing loop member, and each is read by a connection to the FET domain. The memory can be made in various forms. U.S. Patent No. 4,791,6 to 4 issued to Lienau et al. Shows a chip-like random access memory. The chip random access memory is a non-electrical and transportable memory characterized by its cell density and small size and power requirements, but a non-electrical memory with core memory or magnetic disk or tape Characteristics and shock resistance. The chip random access memory is further characterized by a memory including a two-dimensional magnetic substrate and a fixed driving device for writing and reading into the substrate. In addition, a fixed sensing element is attached to each grid position for sensing information. The memory medium includes not only a homogeneous two-dimensional substrate, but also a ferrite core formed in the substrate by photolithography technology. The information is stored in the magnetic core, and the sensing element is used to read 0 from a gap defined by the magnetic core. The memory cell of the invention can be configured and grouped to form serial and parallel destructive reading. Out random access memory, or non-destructive read random access memory 0 US Patent No. 5,926,414 issued to McDowell et al.

Description of the invention (4) Magnetic circuit structure of the magnetic product body combined with a carrier-deflecting magnetic field sensor α Various magnetic structures achieve a state where the magnetic field is substantially orthogonal to Sensing the direction of travel of the current carrier for maximum sensitivity. By arranging a magnetic memory cell on a single minimum size MOS device, a small cell that is more advantageous than the conventional DRAM of a FLASH memory cell can be realized. The greater degree of control over the magnetic field provided by the magnetic structure can minimize the mutual coupling between the cells in a memory array. The U.S. patent issued to Lekven shows a magnetic memory element and a method for producing Most of these components are programs that form static magnetic memory or digital information storage systems. The individual binary storage components are provided with direction-selective magnetic properties by a flux circuit to establish an optimal magnetization axis. The guiding system for driving the individual binary storage components (for storage and sensing) is grouped in a warp. There is a lack of style to achieve selectivity. A batch production program is also disclosed. The purpose and summary of the present invention is therefore one of the features of the present invention is to provide a non-electrically strong magnetic random access memory device that can quickly read the stored data in each magnetic volume.

The read circuit may include a magnetic sensor, which is placed near the strong magnetic link And read the polarity or direction of the magnetic flux current. Now refer to Figures 1 and 2. • The magnetic sensor 7 with magnetoresistive element 1 (referred to as MR1) according to the invention 7 'has a collector 2 along the magnetoresistive element 1. Place it on a selected side. In addition, the input line 3b provides current to the MR1. 9 The output line 3b receives the current from the white MR1. The collector 2 is coupled to the output line 3b so that the current it accepts is directed to the output line 3b. The white line is accepted. 1¾ of input line 3a is biased in a selected direction (left or right), such as Movable indicator arrow 5. The MR1 on the MR1 {JIL is biased due to the MH1 being placed near the magnetic link (not shown), the latter extending its field vertically through the MR1 t, which is below the white sensor 7 and upwards through the pages of the book 0 In the case of Figure 1, the t current is biased to the right due to the residual magnetic field ΔΔ. Yu is applied to MR1 —hi. Therefore, the electrons of MR1 are squeezed to the right, causing most of them to be collected near collector 2. Because the collector 2 is located near the electron collecting place, the current is easy to pass into the collector 2. Therefore, the series resistance of MR1 is effectively reduced or reduced. Figure 2 illustrates the opposite bias procedure. In this case, 9 electrons It is biased to the left by the magnetic field, as indicated by the arrow 5. Of course, T7Γ7, and since collector 2 is on the right side 9 of MR1, the current is conducted away from collector 2. Therefore, it is more difficult for f current to flow to collector 2. Therefore, M is effectively increased. Series resistance of R1. This paper scale applies the Chinese National Standard (CNS) A4 specification (210 χ 297 mm) —101—A7 46 316 7 ____B7_____ V. Description of the invention (8) The current flowing into the collector 2 flows into the output line 3b. The output line 3b is coupled to the sensing line 4, as shown in Fig. 3. When the current is biased toward the collector 2 and the series resistance is reduced, a larger current reaches the output line 3b and the sensing line 4. However, when the current is biased, When the pressure is removed from the collector 2 and the series resistance is increased, a much smaller amount of current flows into the collector 2, passes through the output line 3b, and enters the sensing line 4. Therefore, the magnetic residual at this stage can be determined by the current amount in the sensing line 4. Now refer to FIG. 3; a schematic diagram of a part of a four-by-four random access memory array 1 ϋ 发明 according to the present invention is shown. There are many individual strong magnetic links 6 each surrounded by a coil, also known as a write or drive line 1 3. A magnetoresistive sensor 7 containing an MR1 and a collector 2 disposed thereon is placed near the storage link 6. An input line 3a and an output line 3b are attached thereto. The magnetic field generated by link 6 which has an effect on magnetic sensor 7 is represented by dashed line 8. Please note that link 6 is actually directly below or directly above sensor 7, but it is best to use dashed line 8 to illustrate it in a schematic way. . The control circuit 30 includes a read / write drive circuit 11, a read / write switch 9 (in the form of a FET), and an input amplifier 10. The control circuit 30 is coupled to the write line I3 and the magnetic sensor 70. This dual coupling allows the control circuit 30 to be used during both setting (writing) and sensing (reading) operations. The write drive circuit 31 is also coupled to the write line 13 but at the opposite end. Furthermore, the amplifier 12 is coupled to the sense line 4 as shown. During the write operation of a single memory cell, the control circuit 30 and the write drive circuit The appropriate sections of 31 are selected at the same time. Therefore, the skilled person in the industry will easily understand that the current is guided in the required direction around any given memory cell, so as to set a logic " ϋ " or Η1 " in this link.

Therefore, the skilled person in the industry will easily understand how to read individual memory cells. 0 Please note that with the combination of the same control circuit 30, read circuit 12 and write circuit 31, the required The overall amount of circuit required to operate the memory cell is reduced. Reference is now made to FIGS. 4 and 5; a typical cross-section of a single micron or sub-micron-scale ferromagnetic memory cell element 110 is shown. Specifically, there is a magnetic sensor 7. —The ferromagnetic storage element (or “link”) 6 is placed on the lotus bottom 22, It is surrounded by a write line 13.

The magnetic sensor 7 includes a magnetoresistive body 1 made of a highly mobile semiconductor material such as indium antimonide, and has a collector 3 (shown in FIGS. 1 and 2) placed along an edge portion thereof. The collector can be made of any conductive material known to those skilled in the art and is coupled to the output line 3 b, shown as a single line from the side. Further shown is an input line 3 a from the control circuit 3 ,, attached Connected to the magnetoresistive body 1 at the opposite end of the output line 3 b. Please note that there is no green insulation layer between the sensor 7 and the ferromagnetic link 6, because no potential exists in the configuration in this configuration.

Specifically, the read / write circuit 30 and the write circuit 31 are activated for each memory cell separately. Depending on the current direction of the write line 1 3, a logic v, zero, or, and one are stored separately in a specific link. Advantageously, unlike the old method design, the entire memory array can be disconnected from the power at this time or Close and save all the digital data stored in the array. However, the previous memory design must be updated regularly to maintain the digital data stored in it. Therefore, the present invention will save power by using the older design. In the present invention, To read digital data, the same read / write circuit 30 and the appropriate read circuit 12 are activated together. To be clear, the current is selected from the path to the sensing circuit 7.
